Application of Natural Rubber Latex for Improving Dynamic Response of Sand
Publication: ASCE Inspire 2023
ABSTRACT
Natural rubber latex (NRL), obtained from Hevea brasiliensis trees, is a biopolymer with excellent binding properties. Additionally, solidified rubber has some exciting characteristics, such as high elongation capacity, tensile strength, resilience, film formation, etc. Being extracted from a renewable natural resource, NRL is expected to be a sustainable, environmentally harmless material. The proposed research utilizes natural rubber latex for treating sand to improve its dynamic behavior. NRL treatment of ready-prepared sand specimens was done by permeating NRL solutions into sand specimens with the help of a fluid permeation setup. The dynamic response of NRL-treated sand was evaluated by performing strain-controlled cyclic triaxial tests. The pore pressure development and cyclic degradation of shear modulus were accessed for comparing the response of treated and untreated specimens. The results show that the NRL treatment helps to reduce the excess pore pressure development and cyclic degradation of shear modulus in the sand.
