Study On The Axial Compressive Strength Of Mechanical Pressing Raw-soil Brick With Special Mortar Masonry

The old building has a long history,varied style,and has the characteristics of cool in summer and cool in summer and green.Comp ared with the traditional architecture,it is also cheaper and convenient for local materials.Facing the severe challenge of environmental pollution,ecological crisis and energy crisis,the development of living buildings is of great significance to the construction of a benign cycle of urban and rural ecosystems,the promotion of the diversified development and innovation of green new buildings in the villages and towns in China,and the inheritance of green ecological architecture and traditional architecture.The weak strength of the traditional dry or wet soil,poor waterproof ability,low aseismic property of the adobe building,and the adding of a certain modified material to produce the soil brick can effectively improve the defects of the strength,waterproof and seismic performance of the traditional adobe building.At present,there is no standard standard for mechanical properties of raw soil building in China,and it is of great significance to improve the mechanical properties of the mechanic soil brick masonry as soon as possible.This paper studied the mechanism of axial compression brick,the compressive strength,the elastic modulus and poisson ratio.The cubic compressive strength test and axial compression test are carried out on the special modified mortar,and its compressive strength is obtained,and its modulus of elasticity and Poisson's ratio are obtained by reference to relevant standard standard.The axial compressive strength of masonry with modified mortar is tested,and the axial compressive strength of masonry is obtained.Based on the masonry compression strength model proposed by A.J.Francis,the relationship between the mechanical soil brick,the modified mortar and the axial compressive strength of the masonry is established to study the axial compressive strength of the brick masonry.In this paper,the testing method and test result of the elastic modulus and Poisson's ratio of the mechanical earth brick block,the special modified mortar and the experimental results are provided in this paper.The relationship between the axial compressive strength of the brick masonry of the mechanism and the basic mechanical parameters between the mechanical soil brick and the modified mortar is put forward to fill the standard of the domestic construction industry.White-collar fields provide reference ideas.
