加气混凝土砌块长期承重使用后性能的研究

Study on Performances of Aerated Concrete Blocks under Long-term Loading Used

对在承重结构中长期使用后的加气混凝土砌块的密度、含水率、抗压强度、砌体抗压强度、导热系数和传热系数进行了测试,并将其与新鲜加气混凝土砌块进行比较。研究表明,加气混凝土砌块作为承重结构长期使用后,各项性能仍然与新鲜砌块基本一致,其物理性能和热工性能并未因长期的承重使用而劣化。

The density, water content, compressive strength, masonry compressive strength, thermal conductivity and heat transmission coefficient of the long-term used bearing aerated concrete blocks are researched, and they are comparedwith the fresh bearing aerated concrete blocks. The results show that the properties of the long-term used bearing aerated concrete blocks used as bearing structure are basically the same with the fresh aerated concrete blocks, the physicalperformance and thermal property of bearing aerated concrete blocks do not deteriorate after long-term used.
