摘要:
对水胶比为 0 .5,I级粉煤灰掺量分别占胶凝材料总量 (质量分数 )为 0,0 .2 0,0 .30,0 .4 5和0 .55的砂浆试样,经标准养护 (d) 7,2 8,90,180和 36 5时的抗压强度、浆体非蒸发水量和 CH含量,进行了系统测试 .试验数据经回归分析,发现粉煤灰掺量与砂浆抗压强度、非蒸发水量和 CH含量之间,分别存在很好的线性相关关系 .从中,可以定量研究在不同的粉煤灰掺量和养护龄期时,粉煤灰效应对大掺量粉煤灰水泥基材料的力学性能和水化进程的影响规律
Abstract:
systematic measurements were made on compression strength, non evaporable water and CH content of mortar samples. These mortar samples entrained first grade flyash with a water ash ratio of 0.5 in respective mass fraction of 0, 0.20, 0.30,0.45 and 0.55; and had passed through standard curing for 7, 28, 90, 180 and 365 days respectively. After regression analysis of these test data, it was found that the fly ash entrainment kept well linear correlation with compression strength, non evaporable water and CH content of the mortar. With respect to the effect of fly ash with different entrainment and curing age on the mechanical performance and the hydration course of large amount fly ash cement based material, a quantitative study can be made therefrom with the hope of probing into its regularity.
