EFFECT OF WASTE MARBLE POWDER AND POLYPROPYLENE FIBER ON THE PROPERTIES OF SELF-CURING CONCRETE
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
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 Self-curing concrete (SCC). The experimental investigation was carried out for mix design of M30 grade in 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 an 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. The results signify that the utilization of waste marble powder and polypropylene fiber enhance the mechanical characteristics of self-curing concrete as compared with controlled concrete of air-cured (C0) and moist cured (C0′). The optimum values were 0.5 % of polypropylene fiber and 15 % of marble powder enhanced the mechanical characteristics of self-curing concrete.
