粉煤灰混凝土抗压强度和成熟度之间的规律研究

摘要

The law between the compressive strength and maturity degree of different strength grade fly ash concrete has been studied by the means of different curing temperature,the results showed that the equation of the law was y=a·ln(x)+b,the parameter a was increased by the mixing amount of fly ash increased,and parameter b was opposite,and the equivalent maturity was higher than 600℃·d.%通过设置不同的养护温度，研究了不同强度等级粉煤灰混凝土抗压强度和成熟度之间的规律，结果表明粉煤灰混凝土的抗压强度和成熟度之间呈y=a·ln（x）+b的对数曲线关系，混凝土强度等级越高，粉煤灰掺量越高，参数a越大，b越小；通过计算发现其等效成熟度高于600℃·d。
