加气混凝土墙上抹灰出现裂缝空鼓现象是施工中的常见病。要克服加气混凝土抹灰造成空裂,应该在两方面采取措施:即提高抹灰砂浆与加气混凝土之间的结合性:减少抹灰砂浆固化时产生的收缩应力。通常采用加107胶或钉钢板网的方法解决,但往往不能完全消除墙面的裂缝和空鼓。这是因为加107胶虽然能提高抹灰砂浆的粘结性和保水性,在普
Plastering cracks in the plastering of aerated concrete walls is a common problem in construction. To overcome the air crack caused by the aerated concrete plastering, measures should be taken in two aspects: to improve the bonding between the plastering mortar and the aerated concrete: to reduce the shrinkage stress generated when the plastering mortar is cured. It is usually solved by the method of adding 107 glue or nail steel mesh, but the cracks and hollowing of the wall cannot be completely eliminated. This is because adding 107 glue can increase the adhesion and water retention of plastering mortars.
