薄层砌筑砂浆对B04级蒸压加气混凝土砌体力学性能影响的研究

摘要

对比研究薄层砌筑砂浆和普通砌筑砂浆对B04级蒸压加气混凝土砌体力学性能的影响,并分析其作用机理.结果表明:与普通砌筑砂浆相比,薄层砌筑砂浆保水性能好,水泥浆体在砌块孔隙内形成水化产物,提升灰缝与砌块的粘结能力,从而提高砌体的轴心抗压强度和通缝抗剪强度.%This paper studies on the impact of thin layer masonry mortar and common masonry mortar on mechanics perfor-mance of autoclaved aerated concrete masonry with B04 grade and analyzes the mechanism of action. The result shows that com-pared with common masonry mortar,higher water retention capacity of masonry mortar increasing the adhesive capability between mortar joint and masonry by forming hydration products in the block pore,and improving axial compressive strength of the masonry and straight joint shear strength.
