Abstract

In this experimental investigation, an attempt has been made to study the suitability of fly ash and lime along with sand in the preparation of stabilized laterite-soil bricks. A required numbers of bricks were moulded with a hydraulic press paver block and brick making machine for the various percentage proportionate, such as, 75% Laterite soil + 15% sand + 5% fly ash + 5% lime, 73% Laterite soil + 15% sand + 5% fly ash + 7% lime, and 71% Laterite soil + 15% sand + 5% fly ash + 9% lime, tested as per, IS specification, and the results of dry compressive strength, wet compressive strength, and water absorption were tabulated. Based on the test results, laterite-soil bricks are more stable than the traditional burnt bricks to resist higher compressive loads. Production of laterite bricks, which do not require any special attention in the preparation decreases the threat to the environment by deforestation and Global warming.
