| Abstract | ||
| Superabsorbent polymer (SAP), also known as hydrogels, is a group of cross-linked, puffable polymeric materials. Due to the structure of the three-dimensional cross-linked polymeric network, it can absorb large quantities (can reach 1000g / g) of different activation fluids and swell up based on its specific chemical bonds. Incorporation of superabsorbent polymer particles (SAP) into cement-based materials, is more convenient as the shape, size and distribution of voids and defects can be controlled. In this study we use a super absorbent polymer which is sodium polyacrylate (sp) in several forms, solid (powder) at a rate of (80-100) mesh and 1% of the cement weight, then in balls with a diameter from (2.61 mm) to (3.25 mm) saturated. . Samples were treated (with treated water and air) to compare the effect of the presence of the polymer on the internal treatment and to compare the experimental compressive strength with theoretical ultrasound examination. The results indicated that the samples containing powder and balls maintained good pressure resistance with significantly light weight. | ||
