Study on Application of Concrete Admixture Technology

Abstract:

Mix design of high performance concrete was determined based on the pumping simulation test. It was indicated by test and field application that the trimixture technique and the double mixture technique can improve the pump of concrete, reduce the dosage of cement and the hydration heat; adding expansion agent can prevent harmful cracks in the concrete due to shrinkage stress, improve the compactness and impermeability. The reasonable construction technologies were used in mixing, transportation, pouring, vibrating and curing of the concrete in order to ensure quality of the construction.
