This paper studies the influence of stone dust on adaptability of polycarboxylate superplasticizer and cement by the experiment of paste slump and mortar slump flow. The results indicate that polycarboxylate superplasticizer mixed in mortar increases with stone dust mixed because of large specific surface and water demand of stone dust. There is little effect on fluidity loss

2016-4-15 Compared with the pure cement concrete JS4, the concrete state is improved by mixing granite dust or mineral admixtures, and the needed superplasticizer amount is reduced correspondingly. As the densities of granite dust (2.85 g/cm 3 ), slag powder (2.90 g/cm 3 ) and fly ash (2.60 g/cm 3 ) are all less than that of cement (3.13 g/cm 3 ), the ...
