摘要
结合三河电厂粉煤灰进行了粉煤灰掺量影响混凝土工作性的研究。试验结果表明,在50%掺量范围内,随着粉煤灰掺量的增大混凝土的流动性也在增大,掺入的粉煤灰能够延缓混凝土的凝结时间。
Fly ash is a important addition of high performance concrete . Researches have been done on the effects of amount of fly ash addition on the behavior of concrete based on Sanhe station fly ash in the paper. Results of experiment show that fluidity of concrete increase with the amout of fly ash within 50% addition and the addition of fly ash delayed the eoagulation of concrete.
