加气混凝土制品是一种轻质多孔且具有一定强度的新型建筑材料,它与粘土砖和普通混凝土等建筑材料在应用上有许多不同特性。在北方寒冷地区,建筑施工每年有3～5个月在负温下作业。加气混凝土砌块在负温下进行施工,日前尚无相应的设计施工规程。我们对在负温下砌筑的加气混凝土砌块砌体进行了抗压试验,取得了初步成果。并结合工程实践,对负温下砌筑加气混凝土砌块建筑作了初步研究和探讨,现简介如下。
The aerated concrete product is a kind of new type building material which is light and porous and has a certain strength. It has many different characteristics in application with building materials such as clay brick and ordinary concrete. In cold regions in the north, construction work takes place every year for 3 to 5 months at negative temperatures. The construction of aerated concrete blocks under negative temperature has not been followed by corresponding design and construction procedures. We conducted a compressive test on aerated concrete masonry blocks built at negative temperatures and achieved preliminary results. In combination with engineering practice, a preliminary study and discussion of aerated concrete block masonry at negative temperatures is presented. The brief introduction is as follows.
