Abstract


This paper reports an experimental investigation into the effects of particles size on the compressive strengths of Cement stabilised Compressed Earth Blocks of mix ratio 8% and 10% , (of cement), using varying soil particle sizes of 2mm, 1.25mm, 0.63mm, and 0.40mm. The compressed bricks were crushed for strength at 7 days, 14 days, and 28 days. The results showed that the compressive strength at 7 days were 1.53 Nmm-2 for 2mm; 1.7 Nmm-2 for 1.25mm; 1.8Nmm-2 for 0.63mm; and 1.94 Nmm-2 for 0.40mm. For 14 days, with 2mm, 1.25mm, 0.63mm, and 0.40mm maximum particle sizes the strength were 1.7 Nmm-2, 1.82 Nmm-2, 2.17 Nmm-2, 2.24, Nmm-2. While at 28 days were the strength were 2.34 Nmm-2, 2.83 Nmm-2, 3.49 Nmm-2, and 4.19 Nmm-2 for 2mm, 1.25mm, 0.63mm, and 0.40mm respectively. In summary, the result shows increase in strength with decrease in particle size of soil and increase in days of curing.
