Clay is an earth resource which is taken as a raw material for a vast range of industrial applications because of peerless properties of such clay. Analysis of the particle size distributions of anthill clay, brick clay and roof tile clay with the important parameters were the aims and objectives of the existing research. In the dry sieve analysis, ASTM D422 standard methodology was followed while performing a microscopic analysis of each type of clay using an optical microscope. Based on the requirements of the testing of water absorption and splitting tensile loads, bricks were manufactured from each clay type. As the major outcomes of the existing investigation, there were obtained well graded particle arrangement from roof tile clay, gap graded arrangement from anthill clay and uniformly graded arrangement from anthill clay, lowest PH value from anthill clay, maximum splitting tensile load from roof tile clay brick, maximum water absorption from anthill clay brick, maximum natural moisture content from roof tile clay and relatively higher finer weight percentage of particles from roof tile clay under both microscopic analysis and sieve analysis.
