Fibre-reinforced concretes have been one of the most popular research topics as they tend to improve the properties of concrete, such as compressive strength, durability, flexural strength and other properties. The fibres are produced from organic material, namely banana, coir, sugarcane, bamboo, etc., as well as inorganic material, namely from steel, glass, synthetic material, etc. Glass fibre-reinforced concrete (GFRC) consists of hydraulic cement, aggregates and discrete glass fibres. This present study discusses the effect of glass fibre on the compressive strength of concrete. The glass fibre used for the study is monofilament, 12 mm long and coated with alkaline resistance. Cubes of size 100 mm × 100 mm x 100 mm of M25 grade concrete were cast with the addition of different percentages of glass fibre, i.e. 0.2%, 0.4%, 0.6%, 0.8% and 1% of the total volume at the same water content. The compression strength tests were conducted at 7 and 28 days, respectively. The reinforced concrete with additional glass fibre was compared with the unreinforced concrete. The test results indicate that with the addition of glass fibre, the compressive strengths vary and show improvement in the strengths. Moreover, due to the presence of the random distribution or dispersion of small glass fibres, the cracking of concrete is decreased.
