CHEMICAL STABILIZATION OF GULLIES OF NANKA AND OKO IN ANAMBRA STATE, SOUTH-EASTERN NIGERIA
AbstractThis study investigated the use 2 mL solution each of AlCl3, CaCl2, Ca(OH)2, MgCl2 and CaCO3 chemicals in stabilizing 10 g and 15 g each of two the gullies in Nanka and Oko towns; and tested with a pocket penetrometer to find out the unconfined compressive strength (UCS). The soil particle size distribution (PSD) were determined also, before treating with the chemical solution. The result from PSD showed that the soil samples had high level of sand in both of them, and low clay content. Also, the stabilizing effects of the chemicals show that AlCl3, CaCl2 and MgCl2 had the highest stabilizing strength on both samples, while CaCO3, Ca(OH)2 showed a low strength.
