Technology of High-powered Concrete on Construction

Before construction of the engineering project,concrete is tested and checked in accordance with the technical requirements for selection of cement,sand,crushed stone gradation,particle size,silt carrying capacity and admixture,etc. After the test and check,different mixture ratio is fixed and the order of ingredient investment is decided,and the optimized solution of concrete composition is obtained by comparisons. And the construction technique of pumped concrete has been perfected. The different manners of deposit and vibrating concrete have been applied in diverse structure parts in this paper. The technology improves the engineering quality,quickens the construction speed and reduces the pollution to the surrounding environment,and provides quality housing for inhabitants.
