Exploring the strength characteristics mechanism of green recycled concrete from construction waste
Along with the rapid development of urbanization,the consumption of concrete shows a trend of continuous growth,and the production of construction solid waste also rises sharply.In view of the limited land resources,the intensification of environmental pollution,and the comprehensive consideration of social and economic benefits,the state advocates the concept of sustainable devel-opment and green environmental protection,and regards the application of recycled concrete as an important trend of future urban construction and development.Through uniaxial compression test on construction waste recycled concrete,The results show that the maximum strain of recycled concrete is greater than that of common concrete.Under the same loading rate,the peak strain of reverse bend is stable,which indicates that there is no obvious relationship between the loading rate and the ultimate peak stress.Under the conditions of the same age and loading rate,The elas-tic modulus of rising section of RC test block with different mix proportion is similar,but there is no significant correlation with the design parameters of the mix ratio.
