剪力墙砼烂根是多方面的原因造成的,其主要原因有以下7个方面:1砼水灰比过大,造成烂根1.1成因砼水灰比过大(一般非泵送自拌混凝土>0.6,泵送砼>0.45)时,浆石易产生离析,由于砼浆液的浮力降低,砼在振动棒的振动作用下,浆石不能重新均匀的布置,而石子往底部沉淀,浆液上浮,形成了烂根。这种烂根往往是通透性的,即水能从墙的一边渗透到另一边。1.2预防措施 Shear wall concrete rotten root is caused by many reasons, the main reasons for the following seven aspects: 1 Concrete water-cement ratio is too large, causing rotten roots 1.1 Causes Concrete water-cement ratio is too large (usually non-pumping concrete > 0.6, pumped concrete> 0.45), the stope is easy to segregate. Because the buoyancy of the concrete slurry is reduced, the concrete can not be re-arranged uniformly under the vibration of the vibrating rod, while the stones are precipitated to the bottom and the slurry floats. Formed rotten roots. This rotten roots are often permeable, ie water can penetrate from one side of the wall to the other. 1.2 Preventive measures
