The Research Of Rectangular Hole Lightweight Sintered Shale Brick And Analysis Of Compression Properties Of Masonry

Along with our country energy gradually reduce, pollution is more and more serious,The wall reform office Strongly put forward the slogan about“Promotion of new buildingmaterials”, This topic from the perspective of energy saving, green building materials,Research and development of lightweight rectangular hole sintered shale brick, willreduce the use of coal combustion in the brick making process, The re-use of waste woodmeets the requirements of sustainable development. Also timely appropriate mandatoryprovisions of the country about prohibiting the use of the circular hole brick. This researchwill be instructive reference for the rectangular hole light shale sintered brick production,Promote the market of rectangular hole lightweight sintered shale brick.This topic research and development of the rectangular hole light sintered shale brickwith shale and wood chips as the main material,Through statistical and analytical data ondifferent wood ash and its compressive strength to establish the mathematical model ofwood ash and intensity to determine quantitatively the relationship between them and findthe best mixture ratio satisfies the requirement of nonbearing wall. In the premise ofoptimal mixture ratio, By setting different temperature sintering process, Explore theimpact of temperature leads to cracks and Chemical transformation in this series processof from the initial to the final brick, Find a special sintering process about rectangular holelightweight sintered shale brick. Under the existing norms, Do lime burst comparative test,hoarfrost comparison test and masonry axial compression comparative tests aboutrectangular hole lightweight sintered shale brick and ordinary rectangular hole sinteredshale brick to get results about lime burst test and scumming test, Based on test data,Obtained both elastic modulus and Poisson's ratio by plotting the stress-strain curve.The experimental study determine the mathematical relationship between wood ashand strength, wood ash is about30%, the strength of the brick5Mpa.Sintered shale brickrectangular hole appeared lime burst and scumming is less possibily than ordinaryrectangular hole sintered shale brick. Compressive strength average value of rectangularhole light shale sintered brick masonry according to Code of masonry design.The elasticmodulus of rectangular hole lightweight sintered shale brick is E=2000N/mm2, Poisson'sratio is Q=0.18; The elastic modulus of ordinary rectangular hole sintered shale brick isE=3000N/mm2, Poisson's ratio is P=0.14.
