近年来,砌块墙体已被广泛采用。但常因灰缝砂浆配制不当,使灰缝处产生冷桥。为寻求与轻质砌块热工性能相匹配的保温砂浆,七八年以来,我们进行了多种方案的保温砂浆试验。并已将研究成果应用于实际工程。一、配料方案及砂浆性能我们作了四种保温砂浆的配比及性能试验(表1)。试验和实际工程使用证明:四种保温砂浆中,以珍珠岩保温砂浆较为理想。 In recent years, block walls have been widely adopted. However, due to the improper preparation of mortar mortar, a cold bridge is formed at the mortar joint. In order to seek insulation mortars that match the thermal properties of lightweight blocks, we have conducted a variety of thermal insulation mortar tests since 1978. And the research results have been applied to practical projects. First, the dosing scheme and mortar performance We made four kinds of thermal insulation mortar ratio and performance test (Table 1). The test and actual project use prove that: In the four kinds of thermal insulation mortar, the perlite thermal insulation mortar is more ideal.
