为研究混凝土复合保温砌块砌体的力学性能,进行了12个轴心抗压强度试件、23个沿通缝抗剪强度试件,以及12个弯曲抗拉强度试件的试验研究。研究结果表明,砌体抗压强度和弯曲抗拉强度可以按GB 50003的普通混凝土砌块砌体强度取值;但沿通缝抗剪强度由于缺少砂浆的“销栓”作用,其强度比普通混凝土砌块砌体强度低,建议按GB 50003规定普通混凝土砌块砌体强度的70%取值。
In order to study the mechanical properties of concrete composite thermal insulating block masonry, 12 axial compressive strength specimens, 23 shear strength specimens along the through-seam and 12 flexural tensile strength specimens were tested. The results show that the compressive strength and bending tensile strength of masonry can be calculated according to the strength of ordinary concrete block masonry according to GB 50003. However, the strength of shear strength along the joint due to the lack of mortar “pin” Lower than the average strength of ordinary concrete block masonry, it is recommended that GB 50003 provisions of ordinary concrete block masonry strength of 70% value.
