An Experimental Investigation on Recron Fiber Reinforced Concrete

Abstract

Advances in concrete have been taking place in concrete construction over the past decade. Researches started using different additives such as Recron fibre, metakaolin, coconut fibres, steel fibre, glass fibres etc.a replacement cement which was found to be sufficient for the improvement of the properties of concrete. In the recent times with the use of this fibres has lead to many advantages such as increase in the homogeneity of concrete with reduction in segregation of aggregates, reduction in shrinkage cracks and also rise in strengths like compressive strength,split tensile strength, flexural strength of concrete along with ductility property. For mix design of M30 grade concrete is taken to determine the compressive strength, split tensile strength and flexural strength of concrete. By adding different proportions of 0,0.3%,0.5%,0.7% of Recron fibres to concrete mix and the casting of different
specimens such as cubes, cylinders and beams are done for 7days and 28days. The Strength and workability parameters have been compared to normal concrete and Recron fibre reinforced concrete.For strength parameters the maximum strength was obtained at 0.7% of Recron fiber and the workability decreases with increase in addition of Recron fibre to the concrete.
