effect of superplasticizer on stone dust concrete

May 01, 2009 Then, seven different series were prepared for investigating the effect of MD content on the properties of the SCC. Water/fine material (cement + FA + MD) ratio was designed as the ratio of 0.35 for all concrete mixtures with respect to β p value. A 50 dm 3 batch has been prepared for each mixture. The mixing sequence was composed of homogenizing the coarse aggregates, the sand, the MD and ...

    Study on the Influence of Stone Dust on Adaptability of

    Abstract: 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 when the dosage of stone dust …
