Experimental Analysis on Manufacture of Brick by Partial Replacement of Clay with Stone Dust

Abstract- Due to increasing population the building materials used in conventional period is depleting, so the civil engineers are in the situation to use the waste material effectively in construction works without compromising the quality of the material. This strategy will also help to reduce the effects taking in disposal of waste materials. Bricks are one of the important building material used in construction but due to its nonavailability of resource and its increased self-weight in the structure hollow blocks and solid blocks replace it. In this paper, the main material clay in conventional brick is partially replaced with different proportion of stone dust of percentage 10% 20% 30% effectively. Bricks are moulded with hand and dry it in hot weather for 15 days and burnt the bricks about 1100°C to find the mechanical .and physical properties. For each combination 5 sample of bricks were casted for accuracy in result. Compression test, efflorescence test and water absorption test were conducted and the results are reviewed with conventional property of brick. In this research, the stone dust with 20% stone dust gives optimum result with lower water absorption capacity.

Keywords: Stone dust, replacement for clay in bricks, light weight brick, water absorption.

I. INTRODUCTION

Demand for the construction materials is increasing day to day in housing sectors in both rural and urban areas. Brick is one of the conventional material used in centuries. In world, Asia produced around 87% of bricks. India and china are the major consumers of brick, so an alternative and ecofriendly material to overcome the problem. Stone dust is a by-product from quarrying, it is estimated that 20% of stone dust in an issue of disposal and this creates environmental issues and landfill problems. In this project, the properties and characteristics of stone dust are studied. II. LITERATURE REVIEW Ismail (2007) investigated the potential utilization of organic residues in clay bricks as sawdust, tobacco residues and grass were mixed with clay at (0, 2.5, 5, and 10) percent by weight. Effects on shaping, plasticity, density, and mechanical properties were investigated. It was observed that the fibrous nature of the residues did not create extrusion problems.
