The Important Role of Aggregate in Construction
2021/9/18Aggregates are a raw material used extensively in the construction of streets, concrete, tiles, bridges, and beyond. When you walk around the streets of your city or town, look at the roads and you'll see the aggregates that connect the paths leading from the street to the sidewalk and then to the buildings.

Main Properties of Concrete for Construction
Concrete is a mixture of several materials. At the hardened state, this heterogeneous material becomes stone-like mass. The extensive use of concrete in the construction field has made it a material of huge concern for engineers. To participate in the vast uses of concrete an engineer must know its properties.
