Abstract：
C60 high performance concrete water cement ratio is low, the amount of fine particles, high cohesion, high viscosity, high flow resistance, the pump itself has a certain degree of difficulty, and the mechanism of sand, grain type and multi angular graded poor, with sand high performance concrete not only increases the viscosity of concrete, but also greatly reduce the concrete workability, resulting in high performance concrete pumping more difficult. Through improving the workability of concrete, decreasing viscosity coefficient and improving pumping ability, we can achieve high performance pumping of high performance fully manufactured sand concrete 315 m.
