浅析标准养护条件下普通混凝土强度与龄期的关系

On the relationship between ordinary concrete strength and age under the condition of standard curing

在水利水电工程中,混凝土的抗压强度是其多项性能指标中最重要的一项。水利水电工程一般以混凝土28天龄期的抗压强度作为工程质量验收评判的依据,但水利水电工程的施工往往需要连续性,通过检测前期3天或7天的混凝土抗压强度值,预判28天的混凝土抗压强度结果,不仅能够保证施工质量,而且为水利水电工程混凝土施工的连续性提供科学依据。

The compressive strength of concrete is the most important indicator among many performance indicators in water conservancy and hydropower engineering. The compressive strength of concrete 28-day age is generally adopted as the basis for accepting and evaluating engineering quality in the water conservancy and hydropower engineering. However, the construction of water conservancy and hydropower engineering always should be continuous ; the compressive strength results of 28-day concrete can be judged in advance through testing concrete compressive strength values for 3 days or 7 days in the former stage. The construction quality can be ensured on the one hand, and scientific basis is provided for the continuity of concrete construction in water conservancy and hydropower projects.
