Paper Title:
Experimental Study on Adaptability of Artifactitious Aggregate with Water-Reducers
  Abstract

Two kinds of the representative artifactitious aggregates, namely the calcium-base and silicon-base, were chosen in the experimental study. Through analysis of SEM, it was found that the former’s main chemical component is calcium carbonate with a structure of crystal granules, the later might be a rock of silicon-base in a state of sandwich. Through experiments of the paste fluidity, ZETA potential and concrete test with different water-reducers, it was shown that the calcium-base aggregate, which could be easily used to prepare high workability and high strength concrete with the polycarboxylic water-reducer, bears a lower water-sobbing ability and has a well adaptability with any water-reducer, and that the silicon-base aggregate, a higher water-sobbing ability, a higher ZETA potential value of its powders, a bad adaptability that there might be a problem of producing HPC though using the high property polycarboxylic water-reducer.
