Abstract

Riverbank collapse often occurs along the Saigon River which flows through Ho Chi Minh City (HCMC). One of the influencing factors is the soft ground which is the riverbank composed of. Our research about the ground improvement method using quicklime, rice husks ash so far. Rice straw is newly added to the improved soil in this paper. The Rice straw is expected to improve the failure strain property that is to restrain brittle failure. These mixing materials can be obtained easily and cheaply in Vietnam. A series of unconfined compression tests are carried out to improve the mechanical properties of improved soil. Moreover pH tests are conducted to validate the chemical action of the improved soil and evaluate the effect of improved soil on surrounding environment.
