STRENGTH EVALUATION OF FIBER REINFORCED CONCRETE USING POZZOLANAS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 10
Abstract
High-performance concrete is defined as concrete that meets special combinations of performance and uniformity requirements that cannot always be achieved routinely using conventional constituents and normal mixing, placing, and curing practices. Ever since the term high-performance concrete was introduced into the industry, it had widely used in large- scale concrete construction that demands high strength, high flow ability, and high durability. A highstrength concrete is always a high-performance concrete, but a high-performance concrete is not always a highstrength concrete. Durable concrete specifying a high-strength concrete does not ensure that a durable concrete will be achieved. It is very difficult to get a product which simultaneously fulfills all of the properties. So the different pozzolanic materials like Ground Granulated Blast furnace Slag (GGBS), Silica Fume, Rice Husk Ash, Fly Ash, High Reactive Metakaolin, are some of the pozzolanic materials which can be used in concrete as partial replacement of cement, which are very essential ingredients to produce high performance concrete. It is very important to maintain the water cement ratio within the minimal range, for that we have to use the water reducing admixture i.e. superplasticizer, which plays an important role for the production of high performance concrete. So I herein this project will test on different materials like Ground Granulated Blast Furnace Slag, and Silica Fume to obtain the desired needs. I will use synthetic fiber (i.e. Recron fiber) in percentage 0.2%, 0.3%, 0.4% to that of total weight of composite and casting will be done to find out the optimum percentage of fiber to be used. Finally I will use different percentage of Silica Fume & GGBS with the replacement of cement keeping constant the optimum fiber content and concrete will be casted. Compressive test, splitting test, flexural test will be conducted on the prepared mortar cubes, cylinders & prisms.
