Fiber Reinforced Concrete FRC can be used for a variety, of applications. Fibers are utilized in concrete crack requiring reduction of physical property protection, drying reduction and improved strength and toughness, increased service life and decrease bleeding from water, concrete permeability, and construction value. The utilization of sisal, a natural fiber with increased mechanical efficiency, as reinforcement in an exceeding matrix based on supported cement. The proportion of sisal fiber used in concrete ranged from 0.1% to 2% of concrete and length of fiber 50mm to 60mm fiber length in concrete with aspect ratio. By adding short fibers, tensile strength is improved, thaw resistance is frozen, impact resistance, and concrete brittleness are reduced. In general, fiber does not enhance the concrete strength, as the replacement moment is reduced in the reinforcement of structural steel. This paper also represents fiber limitation content, environmental aspects, and FRC is the modern technical enhancement in the civil substructure. This review paper also describes the compressive strength test, flexural strength test, tensile strength test, impact strength test of FRC sisal fiber effect strength test.

The main objective of this study was to identify alternative source of good quality fine aggregates which is depleting very fast due to the fast pace of construction activities in India. Use of slag sand is a waste material of copper production and fly ash is a waste material of power plants provides great opportunity to utilize it as an alternative to normally available aggregates and cement. For this research work , M35 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0 to 100% and fly ash replacement with cement of 0 to 30%. The fine aggregate was replaced with copper slag as proportions of 0%, 10%, 20%, 30%, 40%, 50%, 60%, 80%, and 100% and cement was replaced with fly ash as proportions of 30% in OPC 53 grade cement. Concrete mixtures are evaluated for workability, Ultrasonic pulse velocity test and water absorption test. The obtained result was compared with those of control concrete made with Ordinary Portland Cement (OPC).

An attempt was made to use the waste water from textile industry for construction purpose, so that the shortage in water can be greatly reduced and the waste water can be suitably disposed for safe guarding the environment. The basic properties of the treated and untreated water from the textile industry were tested and the results were found to be satisfactory such that it can be used for construction purposes. By using the waste water from the textile industry cubes, cylinders and beams were casted and tested for its mechanical properties (compressive strength, tensile strength, flexural strength etc) and the result was found to be satisfactory. Hence the experiment was continued on for durability studies where the corrosion attack was also studied. The results of other durability studies were found to be satisfactory. In this experimental study the results of specimen's casted using treated and untreated textile water were compared with the specimens casted with potable water. Since there was some corrosion, admixtures were added to counter act the same and the results were found to be satisfactory.
