Durability of Fiber Reinforced Mortar - concrete

01/05/1991  The durability properties of four types of fiber reinforced cement composites are compared. The four composites are conventional steel (SFRM), polypropylene, glass fiber reinforced mortar (GFRM), and slurry infiltrated fiber concrete (SIFCON). To accelerate deterioration, the test program consisted of exposure to intermittent drying and wetting ...

Factors Affecting Durability of Fiber Reinforced Concrete

Cement paste and aggregate bond in concrete is damaged at a temperature of 202 o C and about half of the concrete strength is decline at temperature of 427 o C, and 90% of concrete strength is lost at temperature of larger than 927 o C. Fiber provision do not impede concrete failure under this sever condition but it increases fire exposure safe time. The extension of fire exposure safe time ...

Fiber reinforced concrete- Application, Advantage, and ...

The tensile strength of concrete is only one-tenth of the compressive strength of concrete. Cracks develop in the structure during load. Because of the addition of the fiber in concrete cracks forms at the same load but the structure won’t fall apart, it will be held together by these fibers. Let’s see a short Experiment on Normal Concrete and fiber reinforced concrete. Fibers do not stop ...

Fiber Reinforcement Concrete:- Types, Uses And Advantages

Fiber reinforcement concrete is a composite material consisting of cement paste, mortar, or concrete with fibers of asbestos, glass, plastic, carbon, or steel. Such fibers reinforced concrete may be useful where high tensile strength and reduced cracking are desirable or when conventional reinforcement cannot be placed because of the shape of the number.
