Studies on Strength Characteristics of Soil Mixed with Guar Gum

Natural biopolymers discussed as environmentally friendly and sustainable grouting chemicals. This paper presents guidelines for selecting potentially useful biopolymers for strengthening cohesion soil. Soil is a universally available natural material derived mostly from rocks and rocky minerals. As soil is a product of nature, possess an inherently variable and complex character. The load bearing capacity is the most important soil property, which governs the design of pavement Guar gum was identified for the study over a range of concentration (0.5 %, 1.0 %, 1.5 %, 2.0 %, 2.5 %, and 3.0 %). Experimental results of Expansive soil treated with various percentages of Guar gum gel for various water content and cured samples of 0, 3, 7days. Strengthening effect of Guar gum was shown to have greatest effect on expansive soil with curing periods. Depending on biopolymer concentration, the unconfined compressive strength of expansive soil treated with Agar gum biopolymer. Unconfined compressive strength tests over a range of confining pressures also indicated that the biopolymers effectively increased the expansive soil intercept and CBR values of the treated expansive soil.
