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.
Harrisonburg is an independent city in the Shenandoah Valley region of the Commonwealth of Virginia in the United States. It is also the county seat of the surrounding Rockingham County, although the two are separate jurisdictions. At the 2020 census, the population was 51,814.

Gravel is a loose aggregation of rock fragments. Gravel occurs naturally on Earth as a result of sedimentary and erosive geological processes; it is also produced in large quantities commercially as crushed stone.
Bluestone is a cultural or commercial name for a number of natural dimension or building stone varieties, including:
Dimension stone is natural stone or rock that has been selected and finished to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements. Another important selection criterion is durability: the time measure of the ability of dimension stone to endure and to maintain its essential and distinctive characteristics of strength, resistance to decay, and appearance.
A gabion is a cage, cylinder or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, military applications and landscaping.
Swift Run Gap is a wind gap in the Blue Ridge Mountains located in the U.S. state of Virginia.
Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete. Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called urbanite.

Opus 40 is a large environmental sculpture in Saugerties, New York, created by sculptor and quarryman Harvey Fite (1903—1976). It comprises a sprawling series of dry-stone ramps, pedestals and platforms covering 6.5 acres (2.6 ha) of a bluestone quarry.
A-Jacks are a commercially made concrete product used in both open channel and coastal applications. They consist of two concrete T-shaped pieces joined perpendicularly at the middle, forming six legs. They are a product owned and patented worldwide by Poseidon Alliance Ltd.
Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage. The earthworks created for such a purpose are often called the sub-grade or finished contouring.
Adbri, formerly Adelaide Brighton Cement, is an Australian manufacturer of cement, lime and dry blended products.
Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. It is distinct from naturally occurring gravel, which is produced by natural processes of weathering and erosion and typically has a more rounded shape.
The Michigan Limestone and Chemical Company operated the world's largest limestone quarry, which is located near Rogers City in Presque Isle County, Michigan. It was formed and organized in 1910; however, production did not begin until 1912. Ownership of the quarry has changed a number of times, but it is still one of the largest producers of limestone in the United States. The quarry was inextricably interlinked with lake shipping and railroad transportation.
Smith Creek is a 35.5-mile-long (57.1 km) tributary stream of the North Fork of the Shenandoah River in the Shenandoah Valley of Virginia. Its watershed comprises 106 square miles (270 km2) within Shenandoah and Rockingham counties on the western slope of the Massanutten Mountain ridge. Its headwaters lie in Rockingham County just north of Harrisonburg, and its confluence with the North Fork of the Shenandoah River is located just south of Mount Jackson.
Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. Improvements include increasing the weight-bearing capabilities, tensile strength, and overall performance of unstable subsoils, sands, and waste materials in order to strengthen road pavements.
The Derbyshire Dome is a geological formation across mid-Derbyshire in England.
