Research On Cause And Preventive Measures Of Fracture For Small Concrete Block Building

Concrete hollow block can save energy,arable land,reduce the structural weight,to improve labor efficiency,reduce the amount of mortar,improve the utilization of the advantages of building area,However,cracks of small concrete hollow block construction seriously restrict its development. Therefore,a small block building on the crack-depth study of the issue is very necessary and makes sense. Cracks in the building small block for many reasons,control measures are also various forms. This mainly involves the design and construction of small masonry structure characteristics and differences between the causes of cracks in masonry structure,masonry crack control.First,the development of concrete hollow block was introduced and the basic concepts of crack, crack formation , crack development,crack origin, the form of cracks and crack identification. Second, analysis of the small block in the form of cracks in the wall to find out the reasons for cracking the wall. Governance for the next proposed measures to crack the wall foundation. Finally cracking the wall in front of a variety of factors,based on the reasons for the cracking of the rule proposed block wall crack measures. On the proposed various control measures, through the engineering practice, it also proves the correctness of these measures.
