【摘要】：為了研究新研發(fā)的早強(qiáng)抗裂外加劑對不同低溫養(yǎng)護(hù)環(huán)境下水泥砂漿強(qiáng)度及收縮性能的影響,選擇5種不同的養(yǎng)護(hù)環(huán)境(20、10、0、-10、20~-10℃),進(jìn)行抗壓、抗折強(qiáng)度及收縮試驗(yàn)。試驗(yàn)結(jié)果表明:在作為參考的標(biāo)準(zhǔn)養(yǎng)護(hù)環(huán)境下,該早強(qiáng)抗裂外加劑具有優(yōu)異的早強(qiáng)與抗裂效果;在10、0、20~-10℃等低溫及凍融環(huán)境下,該早強(qiáng)抗裂外加劑具有較好的早強(qiáng)與抗裂效果;在-1 0℃的極低溫度下,該早強(qiáng)抗裂外加劑的早強(qiáng)與抗裂性能受到了較大的抑制。
[Abstract]:In order to study the effect of the newly developed early strength crack resistant admixture on the strength and shrinkage properties of cement mortar under different low temperature curing conditions, five different curing environments were selected to carry out compressive, flexural strength and shrinkage tests.The test results show that the early-strength anti-cracking admixture has excellent early strength and anti-cracking effect under the standard curing environment, and it has better early strength and anti-crack effect under low temperature and freezing and thawing environment such as 100.10 鈩，
