ABSTRACT

Abstract: This paper investigates the compressive strength of compressed stabilized earth block (CSEB) by partially replacing the cement (stabilizer) in the block with Waste Glass Powder (WGP). The soil sample was tested for moisture content and as well consistency limits which showed satisfactory characteristics. The two types of waste glass powders considered were those passing through sieve 150 µm with replacement levels varied at 0%, 20%, 40%, 60% and those passing through sieve 75µm with replacement levels varied at 0%, 5%, 10%, 15%, 20%, 25% and 30% respectively. 65 blocks were made with size 225 x 225 x 112.5 mm and cured for 7, 14 and 28 days. Irrespective of the WGP particle sizes used in this study, it was observed for the percentages of cement replacements used (up to 60%) that the compressive strengths recorded were higher than 3N/mm2, the minimum recommended strength for CSEB at 28 days. As no optimum was observed for the addition of WGP to CSEB in this study (the higher the content of WGP in CSEB, the lower the strength), the result suggests that 20% replacement of cement with WGP whether at 150 µm or 75 µm could be used. The compressive strengths recorded at 28 days at this level were as high as 5.14N/mm2 and there was no significant difference in strength performance when compared with the control mix (with 0% WGP) at early stages.
