摘要
随着泵送混凝土技术的普及,现在混凝土结构施工已基本采用泵送混凝土。但由于泵送混凝土更易形成塑性裂缝,当楼面或屋面一旦振捣不密实,楼(屋)面多易出现渗漏。当采取"二振、一墩、三搓"进行混凝土振捣,可以有效的保证混凝土振捣密实,做到楼面或屋面无渗漏实现结构自防水。对于混凝土多孔砖内墙抹灰易出现空鼓、裂缝,结合现场实际,简要介绍通过墙体基层的界面处理,提高抹灰层与基层粘结强度,保证抹灰质量的二种做法。
With the popularization of pumping concrete technology, now pumping concrete has been widely applied in the construction of concrete structure. Leakage ocurred at teh floor plates because of the prasticity cracks can be seen to form easily in pumping concrete. The article briefly introduced two methods of how to improve the bonging strength of floated coat between walls and guarantee plastering quality by interface treatment of walls.
