The aim of this study is to improve the compressive strength of mortar by adding a recycled material (marble powder) at different weights gradually to the mortar. The samples were prepared and treated with different pH solutions to investigate how can effect compressive strength. The results showed that after preparing the sample of mortar by adding different weights of marble powder, the Compressive strength of the sample of (4 gm) weight of marble powder had the highest value comparing with other samples. The compressive strength for the samples were treated with different pH showed that it decreased with increasing acidity (pH from 1 to 6), but the other sample’s compressive strength increased with increasing alkalinity (pH from 8 to 14). At (pH from 1 to 14), the compressive strength was increasing gradually.
