本文根据国内外钢筋混凝土结构防水技术的发展和存在问题,针对混凝土收缩开裂导致渗漏这一主要矛盾,通过深入的研究,提出了以补偿收缩混凝土作为结构自防水的主要材料,从理论上阐明其抗裂防渗原理,以大量的工程实践为依据,提出我国结构防水技术的发展方向. Based on the development and existing problems of the waterproof technology of reinforced concrete structures at home and abroad, this paper aims at the main contradiction of concrete leakage caused by shrinkage and cracking. Through in-depth research, it proposes the main materials of self-waterproofing with shrinkage-reducing concrete, and clarifies theoretically. Its anti-cracking and seepage prevention principle, based on a large number of engineering practices, proposes the development direction of structural waterproofing technology in China.
