原始语种摘要: Abstract(#br)This paper deals with the effect of granular characteristics of fine minerals admixtures on the water requirement of a cement paste for constant workability without water-reducing admixtures. The contribution of the fine mineral admixtures in the granular packing is appraised by the variation of the water requirement as a function of the replacement of cement by the admixtures in the paste up to 100%.(#br)The water requirement of neat fine mineral admixture paste follows an increasing trend towards specific surface area. However, the irregular morphology of particles of some admixtures increases significantly the water requirements.(#br)For very low proportion of cement in the paste, the water requirement and, consequently, the porosity increase significantly in comparison to...
