He Process Features Of Contemporary Concrete Column And Pouring Hole Block Masonry Structure

With the rapid economic and social development,the construction industry rapidly,leading to environmental pollution are increasingly attracted people's attention,the green concrete works are increasingly important.The application of fly ash and waste concrete aggregate in concrete not only solved the corresponding environmental problem,but also a sign of development and progress of science concrete.Making green concrete material,while construction of concrete projects also need green,this green is to reduce the consumption of resources and energy waste,but also to reduce the preparation.Green construction workforce is not only environmental benefits but also has economic benefits,So the whole process of curve characteristics of recycled concrete,fly ash concrete,fabricated masonry structure provide some data support for the greening of concrete projects.By 148 concrete pillars and 4 prefabricated block masonry shear test to study the different factors to influence the whole process of curve characteristics.The main factors affecting this article has stirrup characteristic value,intensity level,recycled concrete aggregate,fly ash,steel category,the shaft member compression ratio,shear span ratio,section type and so on.Test results analyzed by the following aspects:First,the comparative analysis ordinary concrete uniaxial compressive stress-strain curves of recycled concrete and fly ash concrete.Second,all relevant factors for the whole curve shape concrete columns,strain energy damage factor,ductility coefficient,elasticity coefficient.Third,analysis of axial compression ratio member,shear span ratio,section type for prefabricated block puzzle body shear impact seismic energy dissipation.The results showed a good increase that stirrup constraints can improve the strain energy of concrete,increased ductility,while fly ash,recycled aggregates have an adverse effect on the deformation properties of concrete,seismic energy for wall flange member has beneficial effects.Through a comprehensive analysis of the whole process of the curve of recycled concrete,fly ash characteristics of concrete,masonry assembled,their application in concrete engineering has played a catalytic role.
