摘要:
系统测试与分析粉煤灰掺量 (质量分数 )为 0,0 .2 0,0 .30和 0 .4 5的大坝粉煤灰混凝土的力学性能 .试验结果表明,随粉煤灰掺量的增加,养护 2 8d时,粉煤灰混凝土鹅的各项强度也降低 .养护至 90 d时,粉煤灰的影响程度明显减少,且在该养护期内,粉煤灰混凝土各项强度的增进率明显高于未掺粉煤灰的基准混凝土 .
Abstract:
Systematic measurement and analysis were made on the basic mechanical performance of dam concrete mixed up with 0,0.2,0.3 and 0.45 flyash. As shown by test results, various intensity of flyash concrete reduced along with the increase of flyash content after a curing age of 28 days, however, the effect of flyash concrete decreased obviously of the 90th day of curing, and the rate of increase of various intensity were higher than those of reference concrete containing no flyash during curing age.
