Exprimental Study On Mechanical Performance Of Autoclaverd Fly Ash Brick Masonry And Seismic Behavior Of Masonry Walls

Along with the implementation of the principle of sustainable development in the field of construction, the state proposed energy-saving, land section of the wall reform policies. Due to backward production technology, the durability of brick is bad in the early days. So its use is limited. At present, through improving the pressure molding process, the strength and durability of bricks are improved.(1) The autoclave fly ash brick used in the test of the strength of fly ash bricks and bending strength test, analysi of the impact of the autoclave and the compressive strength of fly-ash bricks bending strength factor.(2) The autoclaved fly ash brick masonry axial compressive performances are researched based on experiment. That the mortar strength influence on the compressive strength of masonry is considered. And the mechanical properties are compared with fired clay brick masonry. The working mechanism of compressive masonry are analyzed.(3) The shear performances of along the seam section are research. Normal mortar and special mortar of different strength grade are compared in test. And the shear properties are compared with fired clay brick masonry. Shear strength calculation formula of autoclaved fly ash bricks masonry are given.(4) Autoclaved fly through the brick wall in the chip-week low reciprocating load test, a reasonable analysis of the characteristics of the destruction of the wall and its deformation, strength, stiffness, ductility, energy and so on seismic performance,...
