China is the largest country produce building ceramic and steel in the world.Large amount of industry solid waste such as ceramic polishing residue (PR) and steel slag (SS) were produced during the process.Currently,the majority of PR and SS were directly discharged into landfills, which is an unsatisfactory solution from both ecological and economic points of view.Since the major constituents of PR are SiO2 and A12O3 with some minor constituents such as CaO, MgO, PR can be used as a low-cost raw material in silicate products.An innovative approach of reusing PR and SS as supplementary cementing materials in silicate products was studied in the paper.Composite cementing materials were prepared by lime and supplementary cementing materials, such as PR and SS.Effects of curing conditions, water binder ratio and content of SS and PR on compressive strength,chemical combined water, pore solution pH value and microstructure of lime mixed with SS and PR were investigated.
