Abstract GRP is a composite material made of glass fibers dispersed in a resin, usually polyester, which is widely used in several fields from buildings to furniture to boats. Worldwide, there is a growing use of GRP due to its lightness, high mechanical performance, possibility of production in any shape and ease of installation and good durability. In this study, it adds different proportions of GRP is at 0.5, 1, 2.3, 4, 5, 6% of the cement weight of mortar which made by 1: 3 of cement and sand with using the ratio by weight ,40 from the water to cement weight. The mortar samples cured for 24 hours (from mixing with the water time) when the relative humidity of 100% then submerged under water for various times of a 3, 7, 28 and 90 Days conducted compressive strength measurements and total porosity of the hardened pastes at different times of the cement interaction, and so for the control mortar samples (without the addition of GRP) and samples containing different ratios of residue GRP The study concluded that the optimal ratio to add GRP to cement mortar is 5% for the weight of the cement, and representing the highest improvement in physical and mechanical properties of hardened mortar slurries containing waste GRP. |
