The use of Super absorbent polymers (SAP) in concrete has many positive effects on various properties of concrete. Due to water entraining property of SAP, the concrete is cured internally as well as externally. Due to this type of curing, there is a significant influence on the strength on concrete. This is also achieved due to SAP's crack sealing mechanism which helps when cracks are developed inside the concrete due to hydration process. However, if too much quantity of SAP is added in the mix, it may lead to additional void formation in the concrete mass which in turn would have a negative effect on the hardened concrete. This effect of SAP on concrete leads to improvement in workability and placing on concrete. The main focus of this study would be to test various strengths of hardened SAP induced concrete and to compare them with ordinary M25 grade concrete.
