PREPARATION OF ALTERNATIVE BRICKS BY USING WOOD ASH AND QUARRY DUST

Abstract

Bricks also have been regarded as one of the longest lasting and strongest building materials used
throughout history. On present day manufacturing of bricks with different material like waste material and by-product. .
Our project is about partial replacement of quarry dust and wood ash with normal bricks. The main aim of our project is
to compare the compressive strength of brick, light-weight bricks, minimize the cost of brick and reduce the sand
material in the brick, So for this purpose sand material of 20% of wood ash and 0%, 10%, 20% & 30% of quarry dust by
its volume and then the compressive strength of bricks are established, and the compressive strength of quarry dust and
wood ash partially added bricks is compared with conventional bricks. Before manufacturing the bricks, different
properties of the materials (sand, wood ash, quarry dust) like fineness and specific gravity was also verified. Then with
the help of Universal Testing Machine (U.T.M.) finally their compressive strength is determined. Testing of bricks like
compressive strength, water absorption, specific-gravity, soundness, efflorescence, hardness, structure test also be
verified.
