摘要：Clay soils have been used locally in sokoto to make bricks without stabilizing the soil.The bricks usually experience structural failure such as cracking and seasional swelling when used for the construction of wall. Stabilization simply refers to blending and mixing of materials with soil with the view of enhancing certain properties of the soil. However, this can be achieved by using mechanical method, additive method or modification method.The method used in this study was additive method of stabilization in which proper percentage of lime was added to the red and brown clay soils to improve their strength properties and durabilities. This study carried out the result of the physical test on red and brown clay soils samples and the comprehensive strength of the bricks produced. The liquid limit plastics limit and plasticity index of the red and brown clay soils sample were determined to be 240,16.0, 0.8 respectively. A varying percentage of lime stabilization was used in this research, these are 0%, 3%, 6%, 9% and 12%. Batching weight was adopted in this study. The dimension of the mould of the machine is 225mm x 112.75mm x75mm. Atotal of 30 bricks where produced tested. The curing method adopted was moisture and curing period was 28days and 56days. Fifteen of bricks were produced at each curing period. The bricks were allowed for 24hrs before curing commenced. After the stipulated curing period, the brick samples were tested for compressive strength. At 6% stabilization, the highest average compressive strength was recorded in 28 and 56 days. The value derived was 1.07N/mm2 and 1.19N/mm2 . The highest value obtained is not closer to the stipulated value of 2.8N/mm2 in B.S 5628 apart (1978).
