Study on the Influence of Different Mortar Thickness on Compressive Strength of Autoclaved Aerated Concrete Block Based on ANSYS

Abstract

Based on Ansys APDL software, this paper conducts mechanical analysis on the autoclaved aerated concrete block walls with different thickness of masonry mortar, such as 2mm and 20mm, and explores the law of the influence of the thickness of the Mortar on the compressive bearing capacity of the autoclaved aerated concrete block walls. The test results show that the compressive bearing capacity of autoclaved aerated concrete block wall decreases continuously with the increase of the thickness of mortar joint, the compressive bearing capacity of masonry unit can be greatly improved by thin mortar joint masonry mortar, and the compressive bearing capacity of masonry with 2mm mortar joint thickness is 17.15% higher than that with 20mm mortar joint thickness. Among them, the regression curve equation of the compressive bearing capacity of the masonry unit and the thickness of the mortar is:y=-0.0248x+2.9972.
