Mechanical Property Evaluation of Self-Compacting Concrete Incorporated with Composite Fibre

Concrete is used nowadays in most of the application for its strength and durability. The limitation in the application is due to its brittleness which causes a sudden failure. Even if the concrete is incorporated with fillers like silica fume, fly ash, slags etc. , because of high cement content and low water-cement ratio, it is subjected to early age cracking. To reduce this problem, the application of composite fibre forming hybrid concrete will help in reducing the crack width and improve the load carrying capacity with large amount of deflection before failure. The research led to the study of various engineering properties of different grades of concrete such as compressive strength, splitting strength, flexural strength, relative residual strength, Impact resistance, toughness, durability properties such as resistance to freezing and thawing, sulfuric acid and chloride attack, cracked permeability and effect of elevated temperature is studied with standard experimental investigation. In addition, the study is made with varying the dosage of fibre with varying volumetric fraction between steel, polymeric and glass fibre. Such concrete elements in which the dimensions are altered the efficiency is kept in consideration along with economy to avoid loss in financial and structural aspects.
