摘要

The effects of rubber powder (RP) and fly ash (FA) with various dosages on flexural and compressive strength of recycled mortars were investigated. Experimental results indicated that the single addition of 4 wt.% RP helped to improve the flexural strength of recycled mortars, but the compound addition of RP and FA in recycled mortars reduced the strength, whatever the compressive or flexural strength; the mechanical properties of recycled mortars with or without RP or FA were better than that of ordinary mortars.
