As we all know, the use of phosphorous slag powder(PSP)as admixture can lead to some adverse effects in concrete performance, such as low earlystrength and prolonged setting times.
磷渣粉作为掺合料对混凝土性能产生一些不利的影响，一是早期强度低，二是凝结时间长。

When GCL1 combined with water retaining admixture HEC and air entraining agent, it will further improve the water retaining performance and increase the early stage and long term compressive strength.
As is shown by the results, compared with the blank cement mortar, the fluidity of cement mortar can be improved by using mineral admixture, but the earlystrength reduced dramatically;
