Experimental Study On Basic Mechanical Properties Of Concrete Multi-row Hole Brick Masonry

The traditional sintering ordinary brick to sacrifice the quality clay resources and damage the ecological environment as the price, serious disrupt the sustainable development and the harmony between human and nature. In order to energy saving and environmental protection, the state council and other relevant departments for "forbidden solid" work were deployed and requirements, the provinces also made corresponding "forbidden solid" provisions. Concrete multi-row hole brick is developed by Guangxi Technology University and Chinese Railway 25th inning replacing sintering ordinary brick of new wall materials.However, as a kind of new wall materials, although concrete multi-row hole brick has released the guangxi zhuang autonomous region and recommendable local standards had some demonstration project of actual application. But in order to completing procedures, the perfect and improve local standards, and compiled in wider range popularization and application of the new wall materials, must establish its complete mechanics theory system. This paper is on the basis of the previous tests unfolded.This paper concrete multi-row hole brick masonry basic mechanical test research mainly in the following aspects:(1) Through the compressive strength of the masonry of axis test research, discussing the compression deformation performance, destruction features and its strength theory, and puts forward the suggestion of formula of compressive strength calculation.(2) Through the analysis of test data, it is concluded that the concrete multi hole brick masonry compression stress-strain curve suggest formula is obtained, suggested by the formula of concrete multi hole brick masonry of elastic modulus calculation formula.(3) Through the general seam of masonry shear strength along the experimental research, obtained the shear failure characteristics, shear strength; On the shear strength calculation formula of regression analysis, and put forward corresponding suggestion formula.(4) Through the seam and along the tooth seam bending tensile strength test research on two kinds of forms of flexural performance especially damage forms are analyzed, also on its strength calculation formula is discussed.This analysis method of the article is established on the basis of experiments, through the concrete multi hole brick masonry basic mechanics, experimental study can not only help us a comprehensive understanding of concrete multi hole brick masonry various mechanical properties, promote the new wall materials, but also promote the use of perfecting and upgrading for rules provide test and theoretical basis.
