Effect of Alccofine and Zeolite on the Properties of Concrete Containing Polypropylrne Granules

Reinforced concrete structures are affected by various durability problems during their service life. Innovative materials are required in the field of concrete technology for the better construction of the structure. Keeping in view, the present work has been carried out by replacing the cement partially with mineral admixtures namely, Alccofine and Zeolite in different concentrations and by incorporating Polypropylene granules to the concrete. In the present investigation the specimens were divided into three sets. One made with only OPC as binder i.e. conventional mix, second made with OPC and Alccofine/ Zeolite together i.e. binary mix and, third made with OPC, Alccofine and Zeolite together i.e. ternary mix. The varying percentages of Alccofine and Zeolite has been taken as 10% and 15% as a replacement of cement and the polypropylene granules has been fixed at constant 1% for all mix proportions of concrete. The w/c ratio was adopted as 0.45. DOE method of mix design has been adopted. The compressive strength, flexural strength and tensile strength tests have been conducted after the curing period of 28 and 56 days. Results showed that Concrete with 15% replacement of cement by Alccofine and 10% replacement of cement by Zeolite along with 1% Polypropylene granules had shown significant improvement in various mechanical properties at the age of 56 days. It was also observed that concrete with 15% replacement of cement by Alccofine along with 1% Polypropylene granules had shown significant improvement in various mechanical properties at the age of 28 days. Thus, the conjoint presence of Alccofine/Zeolite along with polypropylene granules yields better than concrete without any admix.
