一年多来我们运用混凝土早期强化养护方法可加速混凝土早期强度的特性,根据现场实际条件采用了温水法、热水法不同养护方法的加速早强与水中养护28天强度进行对比试验,建立推定28天强度回归方程,并在工程中应用,为混凝土强度质量管理及早提供信息,收到了一定成效。本文简要介绍热水法(七小时)早期强化养护推定值在混凝土强度管理中的应用。一、试验简况为了检验混凝土盘间强度波动情况,每组三块试件分别在三盘的混凝土中制取,共取二组试件,一组用于早强养护,一组用于水中养护。早强养护试件成型到放入温箱为一小时(即前置时间),水箱 Over the past year or so, we have used concrete early hardening methods to accelerate the early strength characteristics of concrete. According to the actual conditions on the site, we used the warming water method and the hot water method to compare the accelerated early strength of the different conservation methods with the water conservation for 28 days to establish a presumption. The 28-day strength regression equation was applied in the project to provide early information for concrete strength quality management and received certain results. This article briefly introduces the application of the water hardening method (seven hours) in the early stage to strengthen the maintenance value in the concrete strength management. First, the test profile In order to test the strength fluctuations between concrete panels, each group of three specimens were prepared in three sets of concrete, a total of two sets of specimens, one for early strength conservation, one for water conservation . The early strength curing test piece is molded into the incubator for one hour (ie, the lead time), the water tank
