建筑节能是我国建筑业的一个薄弱环节。根据《民用建筑节能设汁标准》,我国北方大部分地区外围护墙需采用2号墙(49cm),才能达到节能要求,而东北地区则要求更厚。现有外围墙多为37cm 或24cm。为了使现有建筑达到保温要求,同时对新建筑墙体在满足节能要求的前提下减薄墙厚,从而达到降低能耗和造价,减轻建筑物自重,增加房屋使用面积。在南方地区,冬寒夏热,利用建筑物自身的保温层调节温度也很有必要。内墙保温砂浆适应了
Building energy efficiency is a weak link in China’s construction industry. According to the Standard for Energy-Saving Building Design for Civil Buildings, the wall protection in most areas in northern China needs to use No. 2 wall (49cm) in order to meet the energy saving requirements, while in the Northeast China it is required to be thicker. Most of the existing outer walls are 37cm or 24cm. In order to make existing buildings reach insulation requirements, at the same time, the wall thickness of new buildings shall be reduced under the premise of satisfying energy saving requirements, so as to reduce energy consumption and cost, reduce the weight of buildings, and increase the area of use of houses. In the south, it is necessary to use the insulation of the building itself to regulate the temperature in winter and summer. Internal wall insulation mortar adapted
