Abstract

Researchers focused on the study of mechanical behavior of fibre reinforced concrete in a detailed manner. Recent studies were made concentrating on the long term durability properties of the fibre reinforced concrete. The synergistic effect of fibre concrete which consists of two or more fibres shows a correspondingly better performance than single fibre addition. The present study focused on the drying shrinkage and effect on the compressive property due to freeze and thaw cycle. Two types of fibres such as steel and polypropylene fibres were used and a slag based concrete matrix is designed. Long term performance of this slag based hybrid fibre concrete depends on the types, size and dosage of fibre added to the concrete matrix. The test results show a significant variation for different mixes of concrete. Keywords: slag, steel, polypropylene, synergy, shrinkage.
