Study on Strength Properties of Basalt Fibre Reinforced Concrete with Partial Replacement of Cement as Metakolic

Abstract

This paper provides a summary of strength properties of basalt fibre reinforced concrete. It contains short discrete fibres that uniformly distributed and randomly oriented. Basalt fibres are in increasing demand as they improve the tensile resistance and ductile performance of plain concrete, thus reducing cracking and leading to improve durability of reinforced concrete structure. The main objective is to investigate the mechanical properties of basalt fibre reinforced concrete containing met kaolin as partial replacement of cement. The fibres were placed in concrete by 0.3%, 0.4% and 0.5% of its total volume of concrete, for each mix 10% of cement is replaced by met kaolin. Three sets of cubes, cylinders and prisms for each mix of M20 grade concrete were casted and tested after 28 days of curing. Experimental results showed that the addition of basalt fibres up to 0.4% fibre volume together with mineral admixtures improved the strength properties of concrete.
