Development of interlocking block bricks from clayey soil, mixed with bagasse ash and fly ash Development of interlocking block bricks from clayey soil, mixed with bagasse ash and fly ash

Abstract

   This researcher aim to use fly ash and bagasse ash in the production of interlocking blocks made of clayey soil in Surin Province. The cement to soil ratio was controlled at 1:6 and the replacement level of fly ash and bagasse ash were 30 and 40 percent by weight. The amount of water was varied to evaluate the optimum moisture content (OMC) to used in the mixture of interlocking block. Samples were cast and cured in moist condition until the testing age. From the study, the optimum proportions of cement: local soil: fly ash was 0.7:6.0:0.3 which gave the 90-day compressive strength of 110 kg/cm², water absorption was 10.4%. The drying shrinkage was 0.390 % and abrasion resistance was 2.17%. As the results, fly ash is able to partially replace in inter locking block made from local clayey soil.
