Experimental Study on Strength Properties of High Strength Fiber Reinforced Light Weight Aggregate Concrete

M. Devidson | K. Venkateswara Rao [2]


Abstract: The work deals with an experimental investigation of study on strength properties of high strength fiber rein forced light weight aggregate concrete. The purpose of this research is based on this investigation of hooked steel fibers in structural concrete. In Design of concrete structures, light weight aggregate concrete plays a prominent role in reducing the density and to increase the thermal insulation. The use of structural grade light weight aggregate concrete reduces the self weight and helps to construct larger precast units. The work deals with an experimental investigation on strength durability properties of high strength fiber rein forced light weight concrete. The effects of fibers on workability, density and on various strength properties of high strength concrete (M50) grade concrete have been studied. The fiber content varies from 0.5 %, 1 %, 1.5 % 2 % 2.5 %and 3 % by volume of cement is used in concrete. For this purpose along with a Control Mix, 15 sets were prepared to study the compressive strength, tensile strength and flexural strength. Each set comprises of 6 cubes, 3cylinders and 3 prisms. All specimens are water cued and tested at the age of 7and 28-days. Workability of wet mix is found to be reduced with increase fiber content. Super plasticizer is to be used to increase workability. Ductility and bond of concrete is to found to increase in steel fiber reinforced concrete as observed from the Compressive test, Tensile Strength and Flexural Strength tests were performed in the hardened state. In this study optimum percentage steel fibers arrived at the keeping optimum percentage addition of steel fibers constant and replacing granite aggregate with pumice by 10, 20, 30, 40, 50 % by volume, the strength and durability properties of M50 concrete was studied


Keywords: hooked end steel fibers, Compressive strength, Split tensile strength, Flexural strength, light weight aggregate pumice, superplasticizer Gleninum, Durability and H2So4
