Research on seismic performance of waste glass autoclaved aerated concrete masonry walls
In this paper,to improve the utilization rate of waste glass and expand its application in the field of construction,waste glass was ground into powder to replace quartz sand in the preparation of autoclaved aerated concrete blocks.Experimental research and finite element analysis were conducted on the seismic performance of waste glass autoclaved aerated concrete masonry walls.An orthogonal quasi-static test was designed for four walls made of waste glass autoclaved aerated concrete masonry,considering three factors:height-width ratio,vertical compressive stress,and mortar strength.It is shown from the tests that the failure mode of waste glass autoclaved aerated concrete masonry walls is shear failure.The ductility is significantly improved by the addition of glass powder,with the ductility coefficient of waste glass autoclaved aerated concrete masonry walls ranging from 4.74 to 6.00,demonstrating good seismic performance.It is shown from the numerical simulation that the shear resistance of the walls can be improved by increasing vertical stress,reducing the height-width ratio,and improving mortar strength.Among these factors,the height-width ratio is found to have the greatest influence.
