简谈微沫剂的掺入对砌筑砂浆抗压强度的影响

On the Effects of Mixing Little Foam pharmaceutical into the Mortar on the Compression intensity of it

微沫砂浆的使用简化了施工工序,降低了成本,减少了环境污染。微沫砂浆在潮湿条件下养护,抗压强度增长较快,强度增长规律与水泥砂浆强度增长情况相近。微沫砂浆后期强度变缓并略有些降低,同一般水泥砂浆后期强度增长变化情况不同。我们在进行砌体结构设计及施工时,其抗压强度应乘以相应的调整系数,在某些建筑中应慎重使用。

The use of little foam mortar has simplified the construction procedures, lowered costs, reduced environmental pollution. Under the moist condition, the compression intensity of little foam mortar increases greatly and the intensity increasing law is similar to that of the cement mortar. However, in the anaphase, the increasing speed lowers and the intensity increasing condition differs from that of the cement mortar. When designing and constructing the building body, we have to multiply the compression intensity with the corresponding adjustment coefficient and be cautious in using this method in some buildings.
