Stabilgrus

Stabilgrus, also known as stabilized sand or sand-cement mixture, is a construction material primarily used for base courses in road construction and other civil engineering projects. It is composed of a mixture of sand, cement, and water, which when combined, form a stable and durable material.

The primary purpose of stabilgrus is to provide a solid foundation for roads, parking lots, and other paved surfaces. It is typically used as a base course beneath asphalt or concrete surfaces. The material is known for its high load-bearing capacity, making it suitable for heavy traffic areas. Additionally, stabilgrus is resistant to water erosion, which helps to prevent the formation of potholes and other surface defects.

The production of stabilgrus involves mixing sand with a small percentage of cement, usually around 4-6% by weight. Water is then added to the mixture to initiate the cement hydration process. The resulting material is compacted to form a dense and stable layer. The exact proportions of the mixture can vary depending on the specific requirements of the project and the local soil conditions.

One of the main advantages of stabilgrus is its cost-effectiveness. It is generally less expensive than other base course materials, such as crushed stone or gravel. Additionally, the use of locally available sand can further reduce transportation costs. The material is also environmentally friendly, as it requires less energy and resources to produce compared to other construction materials.

In summary, stabilgrus is a versatile and economical construction material that plays a crucial role in the construction of durable and long-lasting paved surfaces. Its unique properties make it a popular choice for a wide range of civil engineering projects.
