Determining the Effect of Wood Sawdust and Sand on the Compressive Strength and Water Absorption of Clay Pavers

The purpose of this research is to see how wood sawdust and sand affect clay paver compressive strength and water absorption. The authors mixed cement-stabilized clay with sawdust from various woods (limba or kambala) and various sands to make paving bricks in this study (white or crushed). X-ray diffraction was used to analyse the mineralogical composition of the clay raw material, which revealed that the phyllite fraction is primarily composed of 95 percent kaolinite and 5% smectite and/or chlorite/smectite interstratified. The compressive strengths of the mixtures “clay stabilised with 4 percent cement mixed with 4 percent kambala sawdust and 5 percent white sand” and “clay stabilised with 4 percent cement mixed with 4 percent limba sawdust and 5 percent crushed sand” were found to be higher. The water absorption rate of the paving bricks ranged from 18.1 to 20.4 percent.
