Effect of Steel Fibres on the Behaviour of a Chemically Stabilised Soil

The paper describes the effect of fibre quantity on the mechanical behaviour of a soft soil stabilised with binders and reinforced with steel fibres. Two types of tests were carried out unconfined compressive strength (UCS) and direct tensile strength (DTS) tests. The results obtained showed that the compressive strength, tensile strength and stiffness changed with the fibre quantity depending on the strain mechanism of each test. In general, the presence of a low quantity of steel fibres had a detrimental effect in terms of UCS while a beneficial effect was found for DTS tests. As the fibre quantity was increased, the UCS tests revealed a decrease in brittleness, while the DTS tests showed brittle behaviour with an abrupt and complete loss of tensile strength after failure. The relationships between compressive and tensile strengths are presented in the paper.
