Some Studies on Steel Fiber Reinforced Concrete
Fibres are generally used as resistance of cracking and strengthening of concrete. In this project, I am going to carry out test on steel fibre reinforced concrete to check the influence of fibres on flexural strength of concrete. According to various research papers, it has been found that steel fibres give the maximum strength in comparison to glass and polypropylene fibres. Hence, in this pr...
متن کاملPolypropylene Fiber Reinforced Concrete - A Review
Polypropylene Fiber Reinforced Concrete is an embryonic construction material which can be described as a concrete having high mechanical strength, Stiffness and durability. By utilization of Polypropylene fibers in concrete not only optimum utilization of materials is achieved but also the cost reduction is achieved. This paper presents a comprehensive review on various aspects Polypropylene F...
متن کاملMicroplane Model M6f for Fiber Reinforced Concrete
The new microplane model M6f for fiber reinforced concrete features several improvements over the earlier versions: (i) An explicit volumetric-deviatoric split to no split transition formulation in tension which eliminates spurious contraction under tension that the earlier models suffered; (ii) tension-compression load cycles are now correctly simulated using the loading/unloading rules prescr...
متن کاملTension Softening Behavior of Fiber Reinforced Concrete
The project aims to study tensile softening behavior of fiber reinforced concrete .Concrete is very much weak in tension but by addition of randomly oriented short crimped steel fibers will change the behavior from brittle to ductile. In the present work, the steel fibers were added at the volume fraction, being 0%, 0.5%, 1%, 1.5% to the normal strength concrete and high strength concrete. The ...
