Superabsorbent polymers (SAP) are new chemical admixtures for concrete that are extremely capable and multiuse. They offer a number of new options for controlling the mixture's free water. They also contribute to the regulator of the rheological properties of fresh concrete and to the decrease of plastic shrinkage by internal healing. This SAP can be used as different from air‐entrainment agents. It is also helpful in reducing the crack width when they appear during the service stage. It thus increases the life span of the structure and also reduces the cost by not allowing any additional repair and rehabilitation of structures. In this paper, specimens are prepared at the addition of 0.5%, 1.0%, &1.5% Super absorption Polymer called Sodium polyacrylate and testing are done at various stages, and conclusions are made based on the results.
