该文根据城乡建设环境保护部发布的《JGJ15—83早期推定混凝土强度试验方法》结合山西的具体情况,进行了30℃热水法,加速养护推定混凝土28天强度试验研究工作。试验结果表明加速养护推定混凝土28天强度问题,可以提前判断混凝土强度,力控制混凝土工程质量,节约水泥,提供了切实可行的方案,可以在混凝土制品厂和施工现场应用。
According to the “JGJ15-83 Early Test Concrete Strength Test Method” issued by Ministry of Urban and Rural Construction and Environmental Protection, combined with the specific conditions of Shanxi Province, the 28-day strength test of pre-determined concrete with hot water method and accelerated curing at 30 ℃ was carried out. The test results show that accelerating the curing of 28-day strength of presumed concrete can determine the strength of concrete in advance, control the quality of concrete, and save the cement, providing a practical solution which can be applied in concrete products factory and construction site.
