摘要：基于国内外研究现状，根据最佳配合比制备气凝胶保温砂浆，研究相关因素对其导热系数的影响。以郑州市某座高层住宅楼为例，对比分析了气凝胶砂浆保温体系与玻化微珠砂浆保温体系的建筑能耗。研究发现，气凝胶保温砂浆导热系数随着温度的提高而增大，并且与其干表观密度呈现线性增加的趋势；与玻化微珠砂浆保温体系建筑物相比，气凝胶砂浆保温体系建筑物的单位面积耗煤量与单位面积采暖费均降低18%。 Abstract: The aerogel thermal insulation mortar was prepared according to the best mix ratio, and the influence of related factors on its thermal conductivity was studied. Taking a high-rise residential building in Zhengzhou as an example, the aerogel insulation mortar insulation system and glass beads insulation mortar were analyzed. The resuts show that the thermal conductivity of the aerogel insulation mortar increases with the increase of temperature, and its dry apparent density shows a linear increase. Compared with the insulation system of glass beads, the aerogel insulation mortar insulation system has a 18% reduction in coal consumption per unit area and heating cost per unit area, which provides a reference for the study of aerogel thermal insulation mortar.
