RESEARCH OF SELF-COMPACTING CONCＲETE PREPARED WITH WASTE GLASS

Self-compacting concrete was prepared with waste glass being used as fine aggregate． The influence of different replacement rate of waste glass on workability，mechanical properties and volume stability of self-compacting concrete was studied． The results showed that the waste glass could significantly improve the slump and reduce the slump loss with time; concrete prepared with waste glass met the requirements of both passing ability and segregation resistance． The mechanical properties were reduced with the increase of waste glass replacement rate． The weakening effect of waste glass was more significant in the higher strength concrete． Fly ash could effectively suppress the volume expansion caused by the waste glass． As a kind of qualified fine aggregate，waste glass could be used to produce a self-compacting concrete with high performance．
