uses high-performance admixtures to shrink waterproof concrete , and controls the coarse and fine aggregates that appear during construction, which not only improves the overall quality of the concrete, but also It can ensure that the impermeability level of the concrete itself meets relevant requirements and standards. The relevant design proportions must be strictly followed to ensure the thickness of the entire waterproof structure. After multiple designs and repeated tests, the pouring method is finally determined. The use of "double mixing" technology, that is, mixing water reducing agent and fly ash, can reduce the amount of cement, reduce the heat of hydration, and minimize the occurrence of shrinkage cracks. All aspects of concrete metering, mixing and transportation need to be monitored throughout the process.
