Abstract
The strength of a fine-grained lateritic soil from three (3) different localities on Abuja – Lokoja road where road failure happen was treated with rice husk ash (RSA), cement and sodium silicate activator (SSA), with varying percentage examined by means of Atterberg, Compaction and triaxial shear tests. The result showed that Conductivity has the highest mean (144.67µS/cm) and followed by TDS (94.00mg/l) while salinity recorded the lowest (0.057mg/l). Also, TDS recorded the highest Standard deviation (1.10mg/l).This was followed by TSS (0.75mg/l) while salinity recorded the least value of (0.0006mg/l). Further, all the parameter of the water samples examined are within the maximum permissible limit of construction works standards. Also correlation analysis for CBR and UCS shows a positive correlation (between the CBR, RHA and the OMC which indicate a direct relationship between the variables.A significant correlation was found to exist between Geopolymer and Kaolin clay powder (r = 0.95, α = 0.05).
Keywords: Construction material, Sodium silicate, Geopolymer, Kaolin clay, Abuja.
