Effects of Compaction Delay on the Properties of Cement-Bound Lateritic Soils
Keywords: Lateritic soils, Stabilization, Compaction delay, California Bearing Ratio, Unconfined Compressive Strength, Maximum Dry Density, and Optimum Moisture Content.
AbstractThis study is an investigation into the effect of 0 to 3 hours compaction delay with half an hour intervals on soil-cement mixes 3,5,8; and 1, 3, 5 percent cement contents by weight of dry soils, for yellow and red lateritic soils respectively. The tests carried out on the cement stabilized soils were the Compaction test (Standard Proctor), the Unconfined Compressive Strength (UCS), the California Bearing Ratio (CBR) test and Durability test. The results obtained indicated that compaction and strength characteristics decreased with increase in compaction delay for both lateritic soils. For yellow and red lateritic soils 5% and 3% cement content respectively were sufficient and compaction delay must not be more than 2 hours. They are good in stabilized form for sub-base and base of light trafficked ro ads with red lateritic soil more economical.
