随着可持续发展战略的推进,建筑节能墙体在一时间成为建筑行业的新宠儿。本文选择4种常用的砂浆材料进行试验,制定针对性的试件,并对砂浆在不同环境条件下的收缩性能进行实验,发现水料比、龄期等对配套砂浆的收缩性有较大的影响,在施工时必须要掌握不同砂浆的特性,从而提高墙体的稳固性。 With the promotion of sustainable development strategy, building energy-saving wall became the new darling of the construction industry for a time. In this paper, four kinds of commonly used mortar materials were selected to test, to develop targeted specimens, and to test the shrinkage of mortar under different environmental conditions. It was found that the water-material ratio, age, Impact, in the construction must grasp the characteristics of different mortar, thereby enhancing the stability of the wall.
