本文介绍某工程采用一次性浇筑,要确保大体积混凝土的质量。除了满足强度等级、抗渗要求及内实外光等混凝土的常规要求外,关键在于严格控制混凝土硬化过程中因水化热而引起的内外温差,以防止出现混凝土裂缝。 This article describes a project using a one-time pouring, to ensure the quality of mass concrete. In addition to satisfying the general requirements of concrete such as strength grade, impermeability requirements and internal and external light, the key is to strictly control the internal and external temperature difference caused by hydration heat during the hardening process of concrete to prevent the occurrence of concrete cracks.
