摘要

The effects of silica fume (SF) on compressive strength of concrete have been analyzed. The compressive strength results of concrete mixed over different water–binder ratios as well as different replacing percentages of SF were analyzed. The results of the experiments showed that when the polymer/binder materials ratio increases, the compressive strength of concrete decreases. A mathematical model has been proposed for evaluating the strength of concrete containing SF. The proposed model provides a probability to analyze compressive strength based on the time of curing in water (t), water to binder materials ratios and SF to binder materials ratios which are shown as (w/b) and (s). This model might serve as a useful guide for increasing concrete compressive strength.
