自防水混凝土是依靠混凝土自身结构来达到防水目的的混凝土。它多用于地下防水工程。要保证自防水混凝土质量,必须从控制混凝土裂缝的产生和提高混凝土密实性人手,并对变形缝、后浇缝的局部处理采取有效措施,以提高其抗渗性能。
Self-waterproofing concrete is to rely on the concrete structure to achieve the purpose of waterproofing concrete. It is mostly used in underground waterproofing projects. To ensure the quality of self-waterproofing concrete, it is necessary to control the concrete cracks and increase the density of concrete manpower, and take effective measures on the local treatment of deformation joints and post-pouring joints to improve their impermeability.
