English Abstract

Increase the amount of gases emission and construction materials waste was lead to increased interest to used recycled materials in building projects.

In this research the effect and interaction of used recycle cement mortar as aggregate to replaced natural aggregate (sand) on cement mortar properties with variable curing time and constant water to cement ratio (W/C = 0.5) used is studied.

Four group of cement mortar were produced (M0, M25, M50, M100) with different recycled aggregate weight percentage (0, 25, 50, and 100) .

The compressive strength, density, water absorption and porosity percentage were tested.

The results shows the compressive strength and density were decreased with recycle aggregate percentage increment in cement mortar composition, while, the water absorption and porosity percentage increased with recycle aggregate percentage increment in cement mortar ,.

The lower compressive strength and density obtained in M100 samples were 26.08 MPa, 1.83 g/cm3, while; the higher compressive strength and density obtained in M0 samples were 32.95 MPa, 2.28 g/cm3, respectively.

the higher water absorption and porosity percentage obtained in M100 samples were 12.05, 18.08, while; the lower water absorption and porosity percentage obtained in M0 samples were 7.86, 15.25, respectively
