Investigation on Properties of Glass Fiber Reinforced Concrete
Main Article Content
The use of Glass fibre Reinforced concrete in infrastructure applications is becoming more popular. Glass Fibre Reinforced concrete are introduced to enhance the overall performance of structures, such as composite bridge decks, beams, bearing walls, etc.It is a well known fact that plain concrete is brittle and exhibits less compressive and tensile strength and it also exhibits cracking. In this paper study was done using different diameters of glass fibres to determine effect on the compressive strength of concrete for 7 days and 28 days by varying diameter of glass fibes . The different diameters of glass fibres taken for study were 6 mm and 12 mm . The percentages of fibres used in concrete were 1% ,2 %, 3 % and 4 % . The 7 days and 28 days compressive strength suggest that there was an increase of 0.035% and 0.042% in strength respectively for 7 and 28 days with the increase in diameter of glass fibres .
