低温环境下复合矿物掺合料火山灰效应试验研究
Experimental Study on the Pozzolanic Effect of Mineral Additives in Low Temperature
摘要
Abstract
A study on the pozzolanic effect of mineral additives including slag , silica fume at low temperatures was carried out with mechanical experiments .The results indicate that the strength of mortar samples decreases gradually with the decreasing of temperature , and the strength of mortar increases with the addition of mineral additives .The strength of mortar samples are improved by adding 15％ slag +3％silica fume to the low temperature at 180 d.The strength of 0.5 w/c is increased by 9％at 10 ℃, and the pozzolanic effect rate is 25 .1％.The strength of 0 .36 w/c is increased by 6％ at 10 ℃, the pozzolanic effect rate is 22 .5％, and the strength is increased by 5％at 5℃, the pozzolanic effect rate is 21 .5％.关键词
