Abstract

In this experimental work, a series of test bricks were fabricated for the various percentage proportionate like a combination of 92% lateraite soil + 3% cement + 5% fly ash, 90% lateraite soil + 5% cement + 5% fly ash, 88% lateraite soil + 7% cement + 5% fly ash, bricks were compacted with a hydraulic press paver block using brick making machine and cured for 7, 14, 21 and 28 days, tested as per IS specification in both required dry and wet condition. Results of dry compressive strength, wet compressive strength and water absorption were tabulated. Test results show that the maximum compressive strength of laterite soil bricks are more than conventional red clay burnt bricks at below 7% cement stabilizer with fly ash. In comparison, of obtaining test results minimum of 3% cement + 5% fly ash binding material is sufficient in order to achieve required compressive strength.
