一、概述建筑节能是我国节能工作的一个重要领域,根据《民用建筑节能设计标准》北京地区实施细则规定,外围护墙最大传热系数K_0≤1.25W/m~2·K。为达到北京地区住宅节能标准,在主体结构工程中,采用复合墙体是建筑节能的有效途径,如果在墙体上抹膨胀珍珠岩,又是构成复合墙体多种方法中成本最低的一种。因此保温砂浆可解决墙体的隔热保 I. Overview Building energy efficiency is an important area of ​​energy conservation in China. According to the Beijing Area Regulations, the maximum heat transfer coefficient of the external wall is K 0 ≤ 1.25 W/m 2 K. In order to achieve the residential energy-saving standard in Beijing, in the main structural engineering, the use of a composite wall is an effective way for building energy conservation. If the wall is coated with expanded perlite, it is the lowest cost among the various methods for forming a composite wall. . Therefore, the thermal insulation mortar can solve the thermal insulation of the wall
