【Abstract】 By adjusting the dosage of gelled material, mixed with composite mineral admixtures, high efficiency water reducing agent, expansive agent, water retention agent test, optimizing the mixture ratio, the self-compacting concrete adapted to the environment of high temperature and with long distance flowing is prepared. And it is successfully applied for the Xian city high-speed reinforcement project, which can not only satisfy the requirements of the casting, but also greatly speed up the construction progress, ensure the engineering quality, and have good social and economic benefits.更多还原
