用增钙粉煤灰配制高强混凝土的试验研究

Tests and Researches on Utilizing Fly Ash Added Calciumto Make High-strength Concrete

本文探讨了利用增钙粉煤灰配制高强混凝土的可行性。研究结果表明，增钙粉煤灰的品质，取代水泥率等因素对混凝土的性能产生直接影响，采用品质较好的增钙粉煤灰取代２０％左右的水泥（超量系数为１．２），可配制Ｃ６０等级的高强混凝土，其它物理力学性能均满足高强混凝土要求。

This paper investigates the faeasibility of utilizing fly ash added calcium to make high-strength concrete. The study shows that the quality of fly ash added calcium and the rate of cement replaced exert an influence on the properties of concrete directly C60 high-strength concrete can be made by replacing 20 percent cement with better fly ash added calcium,which the cofficient of exceedent amout is 1.2,and other properties of the concrete can meet the requirements of high-strength concrete.
