Grapher analysis and the impact of sodium silicate activator on strength of Kaolin-rice husk ash stabilized laterite

Abstract

The aim of this investigation is to assess the possibility of using an eco-sustainablegeopolymerenhancer, through the development of novel technologies that is proficient in offering tools for the soil systems management and enrichment of construction works. The result from this research showed that geopolymer material used will effectively improve cement stabilized lateritic soil at cement 6%, RHA 6%, KCP 8%, GP 8% and SSA 4%, The addition of geopolymer materials lead to reduction in PI of lateritic soil and also changes laterite samples from plastic into non-plastic state. The Optimum RHA and cement content was found at 6% for CBR signify enhancement in the improved soil compared with the CBR of untreated soil. The UCS values were at their peak at 6% RHA. Similarly, The Durov’s illustration demonstrates that there are correlation processes among two or more various facies that occurred within the soil and water system. Both soil and water from the centre of the plain, is sited in triangle 1 and 2, also rich in Ca-Cl plus Mg-SO4 stimulating ion exchange, suspension of evaporate minerals and in turn make the water suitable for road works. Similarly, it was understood that for the samplings improved with higher liquid enhancer content above 8% SSA, lesser compressive strength was gotten. The latter was most likely attributable to the rise in the positive surcharge and the successive revulsion of soil particles within the mixture. Thus, 8 % of SSA was indicated as the optimal value to be added to the laterite soil for micro-structural scrutiny. The results of this scrutiny specify that the advantages ofgeopolymersmake them a useable alternative to conventional binders in numerous industrial environments and in the realization of advantageousartefactsfor geological engineering.
