| Abstract | ||
| Using polymers to modify mortar improve the workability, adhesion, strength, durability of the cement besides improving cure characteristics. Two mixtures of cement-sand were prepared without water. The first is 1:2 cement: sand and the other ratio was 1:1 cement: sand mixture. Unsaturated polyester was added to the two mixtures at different ratios (30:70, 40:60, and 50:50) polymer to cement- sand mixture. The effect of unsaturated polyester was studied on both mixtures by calculating the density besides measuring the hardness and compressive strength of specimens .The addition of unsaturated polyester showed an improvement in these properties and showed that the increase in the unsaturated polyester percent improve the mechanical properties | ||
