To study the Mechanical Properties of M20 Concrete using glass fiber as an admixture

Concrete is the most commonly used material on the earth. It is extensively used in rigid pavements, buildings, dams, bridges etc. This experimental study is all about to use the glass fiber in M20 mix concrete as an admixture. Fiberglass is an immensely versatile material due to its light weight, inherent strength, weather-resistant finish and variety of surface textures. The purpose of this project is to study the mechanical properties of fiber-reinforced concrete by adding different proportions of glass fiber (E-glass fiber). There are multiple type of glass fibers but this experiment is based on E-glass fiber which is the glass wool generally used in the electrical appliances. The percentages of glass fiber were added as 0.03%, 0.06%, 0.09% and 0.12%. From the experiment, mechanical strength was increased from 7 to 28 days and the maximum strength was obtained as 38% whereas 27% of of split tensile strength was found after 28 days by the addition of 0.12% of glass fiber.
