The influence of different temperature on promoting congeals and enhancing performance and the influence of adding amount on the properties (gel-time, compression strength, bleeding, flow degree etc.) are studied for SP-1 system.

研究了SP-1在不同温度下对水泥浆的促凝、增强性能以及加量对水泥浆各项性能（稠化时间、抗压强度、析水、流动度等）的影响。

Research results indicate that X FLOUR has notable effects of fluidizing and water reducing.

研究结果表明：X粉具有显著的流化与减水效应，其流化与减水效果与目前市售掺合料的最高水平相当，明显好于硅灰。X粉与硅灰复合后，仍具有流化效应。X粉产生流化效应的机理，一是增加水泥浆悬浮体系的分散性；二是通过填充效应减少填隙水，增加了用于混凝土流动性的水量；三是增加混凝土混合料的浆体体积。X粉流化与减水效应的发挥，以与高效减水剂双掺为前提。

Cemented waste rock filling can be divided into cemented boulder-sand slurry filling, cemented boulder filling and cemented gravel filling.
