The effect of cement content and compaction delay on cement treated lateritic gravels from North-Eastern Nigeria was investigated in this study. The natural soil and treated soils were subjected to classification, compaction, and California Bearing Ratio (CBR) tests according to British standards. To investigate the effect of cement content, cement was added in the range of 2-10% by dry weight of the soil, while compaction was delayed by 1 hour, 3 hours, and 5 hours respectively. The results showed that the maximum dry unit weight (MDUW) increased with cement content and delay in compaction time. The highest value of MDUW was observed at 10% cement content using BSH compaction energy where the value increased from20.59 kN/m3 to 22.8 kN/m3. No significant trend was observed for the optimum moisture content (OMC). The CBR value of the soil sample was observed to reduce with cement content and delay in compaction time. This behaviour was attributed to clay mineral-cement interaction and slow setting time of the cement-soil mixtures.
