Experimental Study Of Soil Cement Bricks And Characteristics Compressivestrength Of Brick Masonry Wall Article Swipe

This research is intended to provide detailed technical and economic information on the production of compressed cement stabilised soil bricks. These include information on suitable soil types, local stabilisers, stabilization techniques, production of compressed stabilized soil bricks and their economical value and potential. Critical review of related literatures show that soil types, proportions between soil and stabilizer and compaction pressure applied to the moist soil mix affects the quality of the compressed soil brick. Since the soil used to manufacture the stabilized soil bricks are abundantly available all around the Tamil Nadu. Laboratory tests conducted on Perundurai area soil provided more precise and detailed information on the soils grading, plasticity, chemical composition and the result proved the soil’s suitability for brick production. Using the Ordinary Portland Cement manufactured as stabilizer and soil sample from Perundurai, three different series of tests were prepared based on literature recommendations. Tests were conducted on soil bricks performance like compressive strength and water absorption on which the durability of the blocks depend. The effects of compaction pressure on the quality of the soil bricks, the optimum cement content for stabilization and cost comparison with hollow concrete bricks are prepared. The performance characteristics of local stabilizers are evaluated and comparisons are made. The investigation has revealed that from the bricks produced at the varying cement contents from 12% in increments of 2% up to 16% at constant compressive pressure of 10MPa, all the blocks except bricks produced by 16% cement have 21^stday wet compressive strength values well above most of the recommended minimum values for use in structural work. Thus 16% cement is taken as optimum cement content for stabilization of Tamil Nadu soil for brick production. Further increasing cement content results in an increase in the compressive strength value and a decrease in the absorption capacity of the soil brick. Increment of the compaction pressure also improves the compressive strength of soil cement brick. Comparisons of the effects of local brick masonry and soil brickmasonry showed that soil brick masonry has shown better stabilization effect based on the 21^stday compressive strength of bricks. The cost comparison with the conventional wall making material, hollow concrete bricks, has revealed that compressed cement stabilized soil brick is preferred because it is more economical walling material lin itself and permits the use of economical building techniques.
