Developing of Clay Bricks Quality into Community Standard Product using Rice Husk Ash and Perlite

Abstract

The purpose of this work was to find the optimal raw materials mixing ratio in the clay bricks manufacturer into Community Product Standard. (CPS.601/2547). Clay from Nayom Sub-district, Amnat Charoen Province, Mukdahan Sub-district, Mukdahan Province, Chanuwan Sub-district, Roiet Province and Warinchamrab Sub-district, Ubon Ratchathani Province are provided for manufacturers. In traditional process give low and uncertain quality of clay brick, because of non-certain clay and rice husk ash quality. This worked investigation optimal mixing ratio of rice husk ash and Perlite with clay for clay bricks manufacturers with mixing ratio of 0, 2.0, 2.5, 3.0, 3.5 and 4.0%. The result indicated 3.5% of Perlite added into Roiet clay provided maximum compression test at 15.65 MPa. While, maximum water absorption found in Mukdahan clay at 12.07% from 3.0% of Perlite added. Finally, the compressive strength and water absorption of clay bricks which developed from this work could be acceptable into the Community Product Standard.
