Toughness of Polymer Modified Steel Fiber Reinforced Concrete

Abstract

An experimental investigation is carried out to study the toughness of polymer modified steel fiber reinforced concrete. Volume fraction of steel fibers is varied from 0% to 7% at the interval of 1% by weight of cement. 15% SBR latex polymer was used by weight of cement. Cubes of size 150 × 150 × 150 mm for compressive strength, prism specimens of size 150 mm × 150 mm × 700 mm for flexure strength and, specimen of size 150 × 150 × 150 mm with 16 mm diameter tor steel bar of length 650 mm embedded in concrete cube at the center for bond test were prepared. Various specimens were tested after 28 days of curing. Area under curve (toughness) is measured and mentioned in this work.

Elastic Properties of Polymer Modified Steel Fibre Reinforced High Strength Concrete

“…The mechanical properties of polymer modified randomly oriented fibre reinforced concrete such as compressive, flexure, shear, split tensile and bond strengths are investigated by several researchers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] with limited studies on fundamental elastic constants of such composite systems.…”

Pure Shear Strength of PVA Fiber Reinforced Concrete

“…The development of science and technology in materials for concrete has been the most widely developing area around the world [1]. The most famous advantages of concrete is its high compressive strength, high mould ability and structural ability [2]. However there are many defects for concrete materials, such as low anti-cracking performance, bad toughness, low tensile strength and so on [1].…”

“…However there are many defects for concrete materials, such as low anti-cracking performance, bad toughness, low tensile strength and so on [1]. Quick developments in building material knowledge have empowered civil -structural engineers to attain remarkable improvements in security and functionality of building constructed to common needs of the society [2]. Main advantage of addition of discrete reinforcement is its progressive impact on rupture dynamism and ductility [4].…”

“…The consumption of fiber in concrete will gradually remain to the desired choice for projects like construction of airport pavement overlays, bridges industrial floors, offshore structures, TV towers, parking garages, etc. [2]. The use of fibers in concrete aids to save extensive time and cost which can conquered with the reduction in the cost of labours to formulate, place and switch the usual reinforcement [2].…”
