Nagarnaik Professor, GHRCE, Nagpur, India ABSTRACT The scope of this study is to enhance the industry understanding the sustainable utilization of quarry dust, and to identify any gaps in current knowledge. The term sustainable utilization implies the use of quarry dust to their full potential to meet the needs of the present, while at the same time conserving natural resources and finding ways to minimize the environmental impacts associated both with quarry fines production and use. The addition of fine quarry dust with ldpe as waste plastic in concrete resulted in improved matrix densification compared to conventional concrete. Matrix densification has been studied qualitatively through petro graphical examination using digital optical microscopy. The materials were studied using XRD, SEM, E-DAX for natural sand, quarry dust and waste LDPE. This research has been motivated by the economic and environmental concerns over the disposal of wastes with the costs of traditional engineering materials. Key words: Natural sand; quarry dust; waste plastic, XRD, SEM analysis. Cite this Article: B.V. Bahoria, D.K. Parbat and P.B.

INTRODUCTION Research has been done to investigate the use of quarry fines in various concrete applications. The International Center for Aggregates Research (ICAR) identified the use of micro fines (particles below 75 μm) in concrete. Studies suggested that artificial fine aggregate mortars with high fines content had higher flexural strength, improved abrasion resistance, higher unit
