Abstract:

Among most of the challenges faced by concrete the one critical hurdle is lack of curing due to many factors like labours unavailability, scarcity of water inaccessibility of structures etc. The present study involves the use of self-curing agent super absorbent polymers (SAP) as an admixture in concrete which is also added fibers. The fibers are added were Alkali Resistance (AR) glass fiber which has high dispersion and tensile strength in idea to enhance the strength properties of concrete. On the other hand the incredible material fly ash is to be used as partial replacement of cement. The ideology of the investigation in the study is by fixing the SAP percentage as 0.3% of weight of cement and AR glass fibers as 0.03% of volume fraction of concrete and varying the fly ash percentage as 0%, 10%, 20%, 30%, 40% and 50% for partial replacement of cement and to observe the optimum mix proportion for better strength characteristics of fixed grade of concrete (M40). The idea of varying the fly ash content aroused from looking upon the gap in researches that deals with the SAP as internal curing agent and AR glass fibers. Many papers showed that fly ash percentage is fixed and works were carried out. Since optimization of fly ash content is necessary when each different type of concreting are to be tried practically and the same is taken as main goal of this study.
