| 摘 要： | 通过掺加高效减水剂技术实现较低的水胶比,配制粉煤灰掺量40%,60%,70%的大掺量粉煤灰混凝土,并测试了在不同的养护制度条件下大掺量粉煤灰混凝土抗压强度的发展,研究结果表明:通过协调水胶比、高效减水剂的掺量等参数,可以明显改善大掺量粉煤灰混凝土的早期抗压强度。

| Abstract: | This paper presents a study on the preparation of the high volume fly ash (HVFA) concrete, which super plasticizer with carboxylic acid was used m the HVFA and dosage of fly ash is respectively 40%, 60%, and 70%. The compressive strength of HVFA in the simulated conditions in real structures, in standard condition and high temperature are detected. The results denote that proper water binder ratio and dosage of super plasticizer obviously improve the compressive strength of early age for HVFA. |
