Effect of some key factors on the strength of recycled concrete
Because there exists a used cement mortar layer outside the recycled aggregate,there are more interfaces inside recycled concrete,which would result in recycled concrete has different properties from ordinary concrete.In this paper,the effect of such key factors for recycled concrete mix ratio as water-cement ratio,cement strength,sand rate,maximum granule diameter and gradation on the properties of concrete with recycled coarse aggregate was studied by experiment,and the some useful suggestion for mix ratio of recycled concrete was provided.
