Feasibility Study on Fly Ash-Lime-Soil Bricks (FALSB)

Fly ash is generated in large quantities especially by thermal power plants. A lot of research has been carried out for effective utilization of fly ash in building industry. Use of fly ash in manufacturing brick is one such project which is being studied by researchers. The following materials were used for preparing the samples. Clayey soil, Fly ash and Lime In this study ratios 80:10:10, 70:20:10, 60:30:10, 50:40:10 (Fly ash : lime : soil) are taken for manufacturing FALSB. water content for bricks were taken by preparing sample bricks and was found by 50%. FALSB are tested by the compressive strength, water absorption, efflorescence, tolerance and density The highest compressive strength was found in 70:20:10. the water absorption, efflorescence and density value was found in 50:40:10. The tolerance length was 4.6 M, width was 2.6 M, and height was 1.7 M
