Abstract

Due to the increasing demand for construction material and degradation of environment, there is a need to explore alternative construction material from industrial, household waste and recyclable materials. The recycled materials are used as construction materials in the present world looking for alternative construction materials that are economical and environment-friendly. The paper investigates addition of glass fibers at different percentages like 0.1%, 0.2% and 0.3% to the volume of concrete. Glass fiber reinforced concrete consists of high strength glass fiber embedded in a cementation matrix. The inclusion of fiber reinforcement in concrete, mortar and cement paste can enhance many engineering properties of basic materials. An experimental investigation is carried out on the mechanical properties of compressive strength, split tensile strength, nondestructive tests (ultra pulse velocity and rebound hammer) and impact test for the age of 3 days, 7 days and 28 days.


Description

Concrete is a composite material consisting of hydraulic cement, water, coarse aggregate and fine aggregate. Some of the materials like stone structures are formed by the chemical reaction of cement and water. The stone material is brittle which is strong in compression but weak in tension. The weakness in concrete makes it crack under small loads. The formation of cracks is the main reason for the failure of the concrete. To increase the tensile strength of concrete, a technique of introduction of fibers in concrete is used.
