Abstract—This research work investigates and evaluates the effects of Ordinary Portland cement and lime were used as clay stabilizers on the compressive strength of compressed earth blocks with recommendations for the usage of the blocks in the construction industry. The results showed that the addition of sand, lime and cement at various ratios highly improved the compressive strength of the clay blocks made. The highest compressive strength was obtained when 12% cement and 14% lime were added as stabilizers. However the optimum service performance of the blocks in compressive strength was attained at 50% sand with 6% cement and 7% lime added.
