Effect of Silica Fume and Fly Ash on Compressive Strength of Unfired Clay Bricks
Journal Title: International Journal of Modern Research In Engineering & Management. - Year 2019, Vol 2, Issue 9
Abstract
Readily available engineering materials are preferred in construction of different projects due to its low cost. Clay brick being cheaper and easily available is vastly used in developing countries like Pakistan. Even though clay bricks are largely used in Pakistan however no consideration have been exercised in the brick making industry to lower the use of brick making soil and enhance its compressive strength by using certain waste materials which possess clay like properties. This paper presents the results of a study made to assess the effect of Silica fume and Fly ash on compressive strength of unfired clay bricks. For that Silica fume and Fly ash were used in different proportions (from 2% to 10%) to the weight of clay soil to prepare the soil samples of 22cm×11cm×7.5cm and prepared samples were compared with conventional clay bricks of same site in terms of compressive strength. It was observed from results that compressive strength was increased at each different percent both of the materials. Hence obtained results suggest that there is potential to replace brick soil with either Silica fume or Fly ash to produce the unfired clay bricks with higher compressive strength.
