Dynamic Tests of Steel Fiber Reinforced Concrete

Prediction of the Compressive Strength and Dynamic Modulus

strength and dynamic modulus of steel, polypropylene, nylon, and glass fiber reinforced concrete. Previous studies prove that adding fibers to concrete alters the propagation of ultrasonic pulse velocity waves. Therefore, each type of fiber-reinforced concrete will have a unique relationship between ultrasonic pulse

PDF Load-deflection Characteristics of Steel, Polypropylene

Fiber reinforced concrete decreases efficiently the brittleness of concrete, and it improves its characteristics. There are two main types of fibers: steel fibers and polypropylene fibers which have been studied in recent years. The ductility of concrete is an important property that can be increased by using steel fiber reinforcement.

Shear Testing of Steel Fiber-Reinforced Lightweight

Twelve beams were tested under four-point loads, including three normalweight steel fiber-reinforced concrete (SFRC) beams and six steel fiber-reinforced lightweight concrete (SFRLC) beams. The other variables include the shear span-depth ratio (a/d) (2, 3, and 4) and steel-fiber volume fraction (Vf = 0, 0.5, and 0.75%).

1. FIBRE REINFORCED CONCRETE 1.1. GENERAL: The use of fiber reinforced concrete can be tracted in history to the construction of the Roman Coliseum; still, it took several years of strong testimonials for the wide spread use to become main stream, the use of fibers in concrete has gained enormous popularity in the last decade.

Compressive and tensile strength of steel fibrous

The steel fibers increased the dynamic compressive strength by about 10%. The obtained values of the dynamic tensile strength are 3–8 times higher than the values of the static tensile strength. The steel fibers increase the tensile strength by 20–50%. The reinforced sample has shown an increase of dynamic tensile strength by a factor of

Hybrid Fiber Reinforced Concrete -Types, Advantages and

If steel fiber is used we get steel fiber reinforced concrete. Similarly, nylon reinforced concrete, glass fiber reinforced concrete, carbon fiber reinforced concrete etc. are some of the types. A composite can be stated as a hybrid when two or more type of fibers is used in a combined matrix to produce a composite that will reflect the benefit

Dynamic compressive behaviour of spiral steel fibre

This research further investigates the dynamic compressive properties of spiral fibre reinforced concrete (SFRC) by conducting high rate impact tests using split Hopkinson pressure bar (SHPB). SFRC specimens with different volume fractions of spiral fibres ranging from zero to 1.5% are prepared and tested.

BEHAVIOUR OF STEEL FIBER REINFORCED CONCRETE

Steel fibers are widely used as a fiber reinforced concrete all over the world. Lot of research work had been done on steel fiber reinforced concrete and lot of researchers work prominently over it. This review study tried to focus on the most significant effects of addition of steel fibers to the concrete mixes. The steel fibers are mostly
