Project background The large-scale pouring of large hydro power dams, nuclear power plants, high-speed railways and high-rise building foundations requires the use of temperature-controlled concrete. In the process of concrete mixing, the internal volume of concrete hydration heat increases, especially in the high temperature working conditions for mixing generated heat is higher, in the later cur...

1. Influence of cement mineral composition As we all know, there are four main constituent minerals of Portland cement. Their hydration properties are different and their proportion in cement affects the overall properties of cement. Although C3a contributes greatly to the early strength, the hydration heat is several times of other minerals. Therefore, early strength cement with high C3a content ...

C15, C20, C25 and C30 are commonly used for rural self built houses, and the cement is 325# cement. Brick concrete structure: C15 strength is used for foundation cushion, and C20 or C25 strength concrete is used for strip foundation, column, slab and beam. Frame structure: C15 strength is used for foundation cushion, and C30 strength concrete is used for independent foundation, column, slab and be...
