History

Aboriginal people and colonisation

Aboriginal occupation of the Blue Mountains area dates back at least 12,000 years and appears to have intensified some 3000–4000 years ago. In pre-colonial times the region around Portland was inhabited by Aboriginal people of the Wiradjuri linguistic group. [2] European settlement in this region after the first documented white expedition west of the Blue Mountains in 1813 was tentative, largely because of concerns about resistance from Aboriginal people. There was contact, evidenced by sporadic hostility and by the quantity of surviving artefacts manufactured by the Aborigines from European glass. By 1840 there was widespread dislocation of Aboriginal culture, aggravated after 1850 by the gold rush to the region. [1] [3]

Jack Reed, a long-time resident of Portland, recalls how, as a child in the 1930s, he used to go hunting with two Aboriginal men named Jack and Jimmy. He estimated their birthdates as c.1890 and their visits to Portland as quite frequent. As part of the day these men would visit rock engravings (since removed) but never allow Jack to go near them. Neither spoke much English and both hunted with spears and boomerangs. While staying at Portland they camped close to the dam near the Portland Golf Course. Jack also remembers occasional groups of Aboriginal people coming to Portland to hold corroborees for the town's people. [4] [1]

The NSW National Parks & Wildlife Service register lists 19 Aboriginal sites in the immediate area of Portland, typically rock shelters or expanses of rock with archaeological deposits and sometimes with art and / or axe-grinding grooves, open sites with scatters of stone artefacts and carved trees. In 1982 two sites containing scatterings of stone artefacts were discovered in East Portland during an archaeological survey of the Ivanhoe Colliery for Blue Circle Southern Cement Ltd but these sites were not conserved for various reasons. There have been no Aboriginal sites associated with the Portland Cement Works and Quarries Site. [2] [1]

Portland and cement manufacture in Australia

In 1824 Portland cement had been developed in England by Joseph Aspdin, who named it after a pale grey coloured rock associated with Portland, England. Portland Cement is made by mixing limestone with either clay or shale in the right proportions and then burning the mixture at 1,100–1,200 °C (2,010–2,190 °F), a point at which the mixture begins to fuse. [5] The resulting clinker is then ground to produce cement. Portland cement was a far superior building product and it caught on quickly in Europe and especially Germany but was infrequently used in Australia before the end of the 19th century. [6] There is a reference in Australia that locates the earliest experiments with Portland cement at the Portland site in NSW in 1884 by the Cullen Bullen Lime & Cement Company. [7] [1]

In 1863 Thomas Murray first used the Portland site for lime extraction and production. During the 1880s, Currie and Raffan with others bought Portion 52 and formed the Cullen Bullen Lime & Marble Works. By 1889, the Cullen Bullen Lime & Marble Works had become the Cullen Bullen Lime & Cement Company and was producing Portland cement under the brand name of "Kangaroo". The cement was of variable quality and intermittent and production ceased in 1895. The only remnants of cement production from this era are the two bottle kilns in the northwest corner of Portion 52 and the old brick building known as 'Raffan's Mill'. In 1895 the Cullen Bullen Lime & Cement Company failed and was taken over by one of the original partners, George Raffan, and his brother John, who opened the Ivanhoe Lime and Cement Works & Colliery. In 1898 the Ivanhoe Lime and Cement Works & Colliery also failed. In 1899 these pioneering industrialists sold out to the (British-owned) New Zealand Mines Trust through their agent Dr August Scheidel who bought the land, plant, and leases. Scheidel, who "is considered the father of the modern cement industry in Australia", was born in Heidelberg and received his Ph.D. from Freiberg University in 1880. He obtained backing for an investment of £100,000 to build a cement production plant, which became the most successful cement manufacturing plant in Australia, and of which he remained Managing Director until 1918. [8] [1]

The Cullen Bullen Lime & Cement Company plants on the Portland site used eight static charge (bottle-shaped) kilns with millstone grinding, powered by a small steam plant. As high temperatures were necessary, the open end was of small diameter and chimney-shaped to conserve heat and to induce greater draught through the kiln. Layers of limestone, shale, and timber were hand-packed in each kiln, leaving space for a flue. The doors were then sealed and the kilns fired. The resulting batch of clinker was then removed. Two of these early bottle kilns  built of brick with iron ties and turnbuckles  and the milling plant in the northwest corner of Portion 52 stand as historical monuments to the beginning of the cement industry in NSW. [1] [9]

Timeline for Raffans Mill and the Bottle Kilns at the Portland Cement Works Site

Description

Two remaining 19th century brick bottle kilns at north of Portland Cement Works site 1738 - Raffan's Mill and Brick Bottle Kilns Precinct - Two remaining 19th century brick bottle kilns at north of Portland Cement Works site (5056468b1).jpg
Two remaining 19th century brick bottle kilns at north of Portland Cement Works site

The two remaining brick Bottle Kilns (out of the eight built) c.1889 are extremely rare and constructed in brick with iron ties and turnbuckles. These static lime kilns are approximately 14 metres high and 5 metres body diameter and are constructed from standard bricks to a thickness of 540mm. Steel clamping bands have been fitted around the body of the kilns at an average interval of 700mm. [1]

Located on the north west corner of Portion 52, the bottle kilns in close physical relationship with 'Raffan's Mill' c.1889 - a small, single level, nineteenth century brick structure still displaying its mill grinding machinery. Also rare, the mill consists of three separate areas and appears to have been part of a larger complex. The building dimensions are 15.5 metres (51 ft) long, 12.7 metres (42 ft) wide and 6.4 metres (21 ft) high to the peak of the gable. The roof and half of the northern wall are sheeted with galvanised corrugated iron with all other walls being 370 millimetres (15 in) thick brick laid in English bond. The western side of the building has three large hinged door openings, with the northern end having been utilised as a general store. The southern end was once used as a blacksmiths shop. Internally there is evidence of a mezzanine level supported by 300-millimetre (12 in) timber beams, with windows and a number of unidentified operational openings having been bricked up. Through the southern wall, extends a shaft-driven system of wooden toothed gear wheels and four 1,200-millimetre (47 in) diameter Burr Stone Grinding Mills. The millstone grinding plant was installed between 1889 and 1895 to grind the cement clinker from the bottle kilns. It is of cast iron with three granite millstones. The large gear wheels have removable timber cogs held in place by pegs. Originally the plant was connected by belt to a small steam engine which no longer remains. Some surrounding structure have also gone. [9] [1]

Together these groups stand as historical monuments to the beginning of the cement industry in NSW. This group has been classified by the National Trust and also forms a focus of the local LEP heritage listing. The Fenwick & Holmes 1993 study and the NBRS&P; 2003 study all agree that this group is of State significance as an intact remnant of in situ nineteenth century industrial technology. [1]

Condition

As at 5 May 2005, the grinding plant is in good condition although exposed to the weather. Since most of the connecting structures have gone, a scheme to protect the plant would help its conservation. [9] The remnant standing remains of the Raffan's Mill are in reasonable condition, with the shaft driven wooden-toothed gear system exposed to the elements. Some surface rust is apparent and the wooden gears need protection. [5] [1]

Both Brick Bottle Kilns display signs of wear and exposure, but also remain in reasonable condition. One kiln is in good condition and one has lost some bricks from its top conical section. Cracks are apparent between some brick courses while grass and small shrubs are growing from the upper levels [5] [1]

Both the Raffan's Mill building and the Brick Bottle Kilns have lost much of their surrounding infrastructure that was part of the nineteenth century complex. However, the remaining mill and two Bottle Brick Kilns display a relatively high level of integrity and their association to each other and the surrounding landscape remains clear. [1]

Further information

Both Raffan's mill and the Brick Bottle Kilns should be stabilised. This should include the removal of intrusive vegetation, particularly concerning the Bottle Kilns. [1]

Heritage boundaries

As at 4 July 2013, The Raffan's Mill and Brick Bottle Kilns are of State significance as outstanding and rare remnants of a nineteenth century lime and cement manufacturing plant in a still legible industrial landscape. Their development is closely linked to the origin of the associated town of Portland and to the later development of the Commonwealth Portland Cement Works. The Raffan's Mill and Brick Bottle Kilns represent the genesis of the Portland cement industry in NSW and the beginnings of a century of cement production at Portland. [1]

Raffan's Mill and Brick Bottle Kilns was listed on the New South Wales State Heritage Register on 3 August 2012 having satisfied the following criteria. [1]

The place is important in demonstrating the course, or pattern, of cultural or natural history in New South Wales.

Raffan's Mill and the Brick Bottle Kilns are of State significance as 19th century remnants of the site of commercial production of lime and the site of the first commercial production of Portland cement. The Cullen Bullen Lime and Marble Works and the Cullen Bullen Lime and Cement Company were the direct forebears of the Commonwealth Portland Cement Works and their early successes encouraged the establishment of the town of Portland. [1]

The place has a strong or special association with a person, or group of persons, of importance of cultural or natural history of New South Wales's history.

The Raffan's Mill and Brick Bottle Kilns are of local significance for their associations with early pioneers in Portland Cement manufacture in NSW, notably George Raffan and John Raffan. [1]

The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales.

The two bottle-shaped, brick kilns are of State significance for their aesthetic qualities as distinctive examples of nineteenth century kilns and as part of a remnant nineteenth century industrial landscape. They have outstanding local significance and landmark qualities as a picturesque remnant of the first attempt to bring the cement manufacturing industry to the town. [1]

The place has a strong or special association with a particular community or cultural group in New South Wales for social, cultural or spiritual reasons.

The potential social significance of Raffan's Mill and Bottle Kilns has not been researched. [1]

The place has potential to yield information that will contribute to an understanding of the cultural or natural history of New South Wales.

The Raffan's Mill and Brick Bottle Kilns are of State significance for their technical values as rare surviving examples of nineteenth century lime and cement production technologies. They have potential to yield further information, through archaeological investigation, of the early Portland Cement industry in NSW. [1]

The place possesses uncommon, rare or endangered aspects of the cultural or natural history of New South Wales.

The two Bottle Kilns in combination with Raffan's Mill are of State significance for being extremely rare as intact, in situ remnants of nineteenth century industrial technology. It is very unusual to find such a legible industrial site of this age in NSW that still clearly displays its relationship to the landscape that provided the raw materials as well as the relationship between milling of limestone and the baking of cement. This rarity and significance is enhanced by the juxtaposition of these relics to the continuing use of the Portland Cement Works Site, nearby, throughout the twentieth century for much larger-scale quarrying and commercial manufacture of the same product. The surviving mill machinery attached to the Raffan's Mill building are rare surviving examples of use of hardwood pegs as teeth in the mill wheels and cogs. [1]

The place is important in demonstrating the principal characteristics of a class of cultural or natural places/environments in New South Wales.

The Raffan's Mill and Bottle Brick Kilns are of State significance as fine examples of nineteenth-century lime and cement making equipment. They are outstanding remnants of an industrial enterprise interrelated with the genesis and development of a rural town, as well as the precursor to a larger cement-making complex that operated through much of the twentieth century.

A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource.

<span class="mw-page-title-main">Portland cement</span> Binder used as basic ingredient of concrete

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, and then grinding the clinker with the addition of several percent gypsum. Several types of portland cement are available. The most common, historically called ordinary portland cement (OPC), is grey, but white portland cement is also available. Its name is derived from its resemblance to Portland stone which is quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. His son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s.

Cement kilns are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology. Emissions from cement kilns are a major source of greenhouse gas emissions, accounting for around 2.5% of non-natural carbon emissions worldwide.

Rosendale cement is a natural hydraulic cement that was produced in and around Rosendale, New York, beginning in 1825. From 1818 to 1970 natural cements were produced in over 70 locations in the United States and Canada.

The Rosendale region of southeastern New York State is widely recognized as the source of the highest quality natural cement in North America. The Rosendale region was also coveted by geologists, such as W. W. Mather, a geologist working for the State of New York, for its unusual exposed bedrock. Because of its reputation, Rosendale cement was used as both a trade name and as a generic term referring to any natural hydraulic cement in the US. It was used in the construction of many of the United States' most important landmarks, including the Brooklyn Bridge, the pedestal of the Statue of Liberty, Federal Hall National Memorial, and the west wing of the United States Capitol building.
