Influence of recycled fine aggregates on strength properties of reactive powder mortar

Abstract EN

Though lot of research has been reported on recycled aggregate concrete, very little information is available about the influence of using recycled aggregate in the production of reactive powder Concrete.

An experimental work was carried out to investigate the influence of using recycled concrete as fine aggregate in reactive powder concrete.

Five different mixes were prepared, the first mix, or control mix, was prepared with natural sand, four additional mixes were prepared with different percentage of substitution of fine aggregates(20%,40%,60% and 80%) .

The investigation was carried out using compressive strength test, direct tensile strength test and flexural strength test.
