Student thesis: Master's Thesis


Earth blocks are generally brittle weak and vulnerable to damage Cement and lime have been used as a stabilizing agent to improve the compressive strength and water absorption capacity of compressed stabilized earth blocks (CSEB) and also make them suitable for construction Stabilizers are usually blended with industrial by-products to enhance the engineering properties as well as to get rid of waste In Taiwan the disposal of reservoir sludge has become a big issue The reservoir sludge mainly consisting of smectite clay is organomodified by a cationic exchange reaction and becomes hydrophobic This research outlines the results of an experimental study to assess the effects of Organo -Modified Reservoir Sludge (OMRS) on Compressed Stabilized Earth Blocks (CSEB) Earth blocks Stabilized with various percentage of Lime-OMRS Cement-OMRS and plain Cement were produced and tested for compressive strength and water absorption tests Experimental results reviled that the optimal dosage of OMRS for Cement-OMRS stabilizer is 3% and for Lime-OMRS stabilizer is 1% by weight OMRS powders served as fine aggregates were as filled in the void spaces to create a denser CSEB which leads to higher compressive strength and lower water absorption value compared to that of plain cement stabilizer
