Engineering properties and behaviours of stabilized compressed tropical soils

S. A. Ola

Department of Civil Engineering, University of Benin, Benin City, Nigeria

This paper summarizes the work done so far on stabilized compressed tropical soils as a replacement for sandcrete blocks. The study shows that the effects of compaction far outweight the effect of cement content in a compressed block; however, compaction pressures greater than 8 MN/m2 will increase neither the tensile strength nor the compressive strength significantly. The ratio {surd}length x breadth/thickness is a very important ratio for compressed blocks, and the crushing strength increases with the increase of this ratio for constant compaction pressure and constant cement content. Thus the cinva-ram press will give the highest strength whilst the tek-block will give the lowest strength. The work recommends a minimum wet (soaked) strength of 1.4 MN/m2 for soilcrete blocks, and 2.8 MN/m2 for dry strength to be used for building. For the most economic benefit, a compactive pressure of 4–8 MN/m2 and a cement content of 5–9% are recommended for a commercial soilcrete venture.
