海工大体积混凝土耐久性控制

Durability Control of Marine Structure Mass Concrete

在建设工程中大体积混凝土常见的质量问题就是混凝土结构产生裂缝,为防止裂缝产生,不仅要满足强度、抗渗等要求,还要严格控制大体积混凝土内外温差。结合工程实际经验,从胶凝材料用量的控制、原材料的质量控制、正交设计法的运用等方面探讨大体积混凝土的耐久性,以期达到提高大体积混凝土质量的目的。

Common quality problems of mass concrete in construction is the formation of crack,In order to prevent the formation of crack,the requirement of strength and anti-permeability should be meet and Internal and external temperature differences should be controlled. Durability of mass concrete is discussed from controls of cementing material amount,controls of material quality and application of orthogonal design with the construction experience to improve the quality of mass concrete.
