Optimization of Ultra-Fine Limestone Filler on Cement Grain Composition

Abstract:

An experimental investigation was carried out to evaluate the effect of limestone filler (LF) with equivalent replacement of cement on its grain composition. The results indicated that LF optimized cement particle distribution, filled the empty place among cement particles and released more free water when mixing. With the decrease of the LF particle size and the increase of LF replacement ratio of cement, these effects were more remarkable. As a result, the finer and the more replacement ratio of the microfiller, the lower the flow resistance and plastic viscosity of the mixture from a rheological point of view.
