Experimental Investigation on Mechanical Properties of Hybrid Fibre Reinforced Concrete Due to the Influence of High Volume Fly Ash
D Nissi, K Venkatesh
Abstract: Concrete is a material made out of Cement, Fine aggregate, Coarse aggregate and water. It is notable that assembling of one ton of Ordinary Portland Cement (OPC) assimilates 4GJ energy and produces about 0.75 to 1.0 ton of CO2 to the aerosphere. To add to a decrease of utilization of concrete around the world, industry wastages like Fly ash, Ground granulated slag, Silica seethe, Rice husk debris and so forth, have been started by scientists to supplant OPC in the solid. The concrete creation measure delivers a ton of carbon dioxide in air, which is the essential ozone depleting substance that causes a worldwide temperature alteration. Thus substitution of an extensive part of concrete by Fly ash can make a significant commitment towards tackling the worldwide temperature alteration issue. There has been an expansion in utilizing of High Volume Fly Ash Concrete (HVFAC) lately and various papers have been distributed. High Volume Fly Ash (HVFA) is commonly characterized as that with in any event half of the Portland concrete supplanted with fly debris. It is important to utilize super plasticizer on account of exceptionally low water content in High Volume Fly Ash concrete (HVFAC). Fiber reinforced concrete (FRC) is a concrete containing fibrous material which increases its structural integrity. The addition of Steel Fibers in concrete significantly increases its flexural toughness; energy absorption capacity, ductile behavior prior to the ultimate failure, reduced cracking, and improved durability. The Mechanical properties like Compressive strength, Flexural strength, Split tensile strength of high volume fly ash concrete reinforced with hybrid Fibres shows significant improvement of strength properties beyond 28 days.
