EFFECT OF WASTE MARBLE POWDER AND POLYPROPLENE FIBER ON THE PROPERTIES OF SELF-CURING CONCRETE: Mohammad Abid & Khushpreet Singh - Tapa blanda

Sinopsis

Globally the value of water and natural resources is increasing day by day. From that point of view, it is desired to put efforts to find out techniques to safeguard water from wastage and utilize the waste materials. The utilization of these waste materials could have a significant effect on hardened characteristics of the concrete. However, the use of a self-curing chemical agent has a positive effect on concrete. The moisture distribution from the atmosphere can also change the mechanical properties of concrete. In this study, Polyethylene-glycol 400 was designated as a self-curing agent along with waste marble powder and polypropylene fiber to determine the mechanical characteristics of a Self-curing concrete (SCC). The experimental investigation was carried out for mix design of M30 grade in an SCC with 1 % Polyethylene-glycol 400, and (0.5, 1, 1.5) % of polypropylene fiber as in the concentration of cement. It also defines the usage of different percentages, such as (5, 10, 15) % of waste marble powder as a partial replacement of fine aggregate in a SCC. Various tests had been conducted on hardened properties of SCC, such as [Compressive, Flexural, and Tensile] strength, X-ray Powder Diffraction (XRD), Scanning Electron Microscopy (SEM) & Energy Dispersive X-Ray Spectroscopy (EDS) to evaluate the strength properties of SCC.
