| 摘 要： | 考察了混凝土配合比中水胶比和粉煤灰掺量的变化,以及养护龄期的增长对粉煤灰活性因子的影响.研究结果表明:随着水胶比和粉煤灰掺量的增加,粉煤灰的活性因子减小;随着养护龄期的延长,粉煤灰的活性因子增大.同时,采用多元非线性同归方法,得出了粉煤灰的活性因子随水胶比、粉煤灰掺量和养护龄期的变化规律,随着水胶比和粉煤灰掺量的增加,粉煤灰的活性因子呈线性下降,随着养护龄期的延长,粉煤灰的活性因子呈二次曲线增长.

| Abstract: | The influence of water to binder ratio,fly ash content,and curing time on fly ash activity factor are studied.Experiment results show that,along with the increase of water to binder ratio and fly ash content,the activity factor of fly ash is decreased,and along with the increase of curing time,the activity factor of fly ash is enhanced.By applying multivariate non-linear regression method,the influence tendency of water to binder ratio,fly ash content,and curing time on fly ash activity factor is gained.Alo... |
