order to examine the elemental composition and the morphological images (see appendix). From where the Bambey laterite was chosen specifically from Ngoundiane pit. − Secondly, sieve analysis test has been performed to determine each type of soil that we brought at the Oregon state university, Civil and Construction engineering facility. − Once the mixture and compaction test were performed on the laterite sieved at 0/20 to find out the optimum moisture content (OMC) at 10.2% and Maximum dry density (MDD) at 2.06 g/cm 3 , and with obtained OMC and MDD: • A certain concentration of calcium silicate (CaSiO3) has been fixed, mixed and compacted with each soil sample using standard molders 100/150 mm or 3.75’ / 4.375’. • The percentile of Calcium silicate is fixed to 4% added in the laterite specimen and 6% added in the black clay specimen soil, as which the studies have shown earlier. • The unconfined compressive strength has been performed to find the unconfined compressive strength (UCS) of the laterite soil and the black clay treated soil. • The consolidation part of test has been performed to evaluate the rate of compression for the untreated or treated black clay specimens and the untreated finest particles of clay found in the laterite specimen. − Finally, the results are compared for each type with cement additives at the same percentiles. IV. E xpected O utcomes It is expected that these soils specimens are stabilized, and their engineering properties are enhanced using that chemical additive at the appropriate content. V.
