Experimental Study on Mechanical Performances of Magnesium Lightweight Wallboard with Used in Exterior Wall

Abstract:

Magnesium lightweight wallboard is a new kind of building wall materials in recent years. This wallboard has a light weight, and has the advantages of energy conservation and environmental protection, increase the use area of the buildings, easy to install and improve construction efficiency, etc. This paper designs one 1:1 cast-in-situ concrete frame of span 4.5m and net height 3.3m, and embed magnesium light wallboard in it. Applying level force with simulates wind load to the wallboard. In the experiment adopted two wallboards with different thickness and different connection ways with wallboard and frame. During the test observe the development of cracks, measured the horizontal displacement, the cracking load and ultimate load of wallboard. Test results show that the strength and displacement of wallboard can satisfy the requirements of the use of exterior walls, which can be used to building external wall with a certain height.
