Abstract
With the growing concern of awareness regarding sustainable building materials and environmental issues, a number of people have resorted to using soil-cement stabilized blocks (SCSBs) as an alternative for burnt bricks. However, these stabilized blocks are also known for their high-water absorption capacity during wet seasons which affects their strength and durability. The study conducted involved a series of physical properties tests of soil (particlesize distribution analysis and Plasticity Index test); mechanical property tests (compressive strength test and water absorption test), which were undertaken in accordance with the ASTM standard. It compared the compressive strengths and water absorption capacity amongSCSBs with a sand blend at different proportions of mixture (10%, 20% and 30%) and those without sand, maintaining thequantity of cement constant at 5%. The results indicated that the compressed stabilized earth blocks using silty clay soil blended with sand and with 5% cement were stronger compared to those without sand. However, the water absorption capacity of the blocks (both with and without sand), revealed no significant difference except for the blocks with 20% of sand which proved to have the lowest water absorption capacity (15%). The SCSBs of 10% addition of sand proved to be the strongest with compressive strength of 2 Mpa. The study concluded that 10% blend of sand could be adopted in block manufacturing for sustainable low-cost housing construction. Having known the strength of these blocks, the users can go ahead and use them in low cost housing construction projects.
