Development of high performance geopolymer concrete with waste rubber and recycle steel fiber: A study on compressive behavior, carbon emissions and economical performance

•Rubber powder and recycle steel fiber form waste tyres are adopted to modify high performance geopolymer concrete.•Compressive behavior and mechanical mechanism of R-HPGC were investigated.•A compressive stress–strain model of R-HPGC considering the crumb rubber replacement ratio is proposed.•A carbon emissions and economic evaluation method is proposed.•Carbon emissions and economic performance of R-HPGC, UHPC and NC are evaluated and Compared.
