Abstract

Natural biopolymers discussed as environmentally friendly and sustainable grouting chemicals. This paper presents guidelines for selecting potentially useful biopolymers for strengthening cohesionless soil. Guar and Xanthan were identified for the study over a range of concentration (0.5%, 1%, 1.5%). Unconfined compressive strength test performed for sand treated with various percentage of biopolymer for various water content and air dried of 3, 7, 28 days. The guar and xanthan create gel matrices and indirectly with the sand particles on surface (e.g. coating), between particle-to-particle contacts (e.g. cementation). Strengthening effect of Guar and xanthan gum was shown to have greatest effect on poorly graded sand with fine particle and with air drying periods.
