How Much Do You Know About Concrete?
Concrete is a common building material in civil engineering and is widely used in all kinds of civil engineering. It is mainly used in the structural parts of buildings, such as foundations, walls, beams and columns. Concrete has high strength, durability and good plasticity, which makes it an ideal material for building high-rise buildings, bridges, roads and other infrastructure. Mass concrete refers to mass concrete with the minimum geometric size of not less than 1 meter, which is often used in high-rise building foundation, large equipment foundation, water conservancy dam and other projects. Because of its large volume, concentrated release of hydration heat of cement and rapid internal temperature rise, it is easy to cause temperature cracks, so it is necessary to pay special attention to the hydration heat and the volume deformation caused by it. Permeable concrete is a kind of building material with good permeability, which is widely used in roads, sidewalks, squares, parking lots and other places. It can effectively drain water, prevent water accumulation and flooding, reduce the consumption of groundwater resources and improve the utilization...
