早期推定混凝土强度的应用研究

Application Research of Concrete Strength Estimation in Early Age

将早期推定混凝土强度试验方法应用于混凝土配合比设计中。在大量试验的基础上,建立了工地常用几种水泥的强度关系式,采用早期推定混凝土强度的方法,缩短配合比试配试验的时间,及时发现水泥质量问题。实践证明,此方法对普通硅酸盐水泥和复合硅酸盐水泥具有很好的适用性。

The method of concrete strength estimation in early age was used in mix proportion design. Based on a lot of testing, some cement strength formulas often used in the site was established. Adopt estimate method of concrete strength in early age, the period of ratio test will be shorten, and cement quality can be controlled in time. The practice prove that this method has perfect applicability for common Portland cement and compound Portland cement.
