Mechanical Behaviour of Conventional Concrete Using Fly Ash and Steel Fibre

Abstract

Concrete that area unit victimization with the waste materials, recycled materials etc. could be a revolutionary topic at this time of concrete business. This kind of concrete that resembles the traditional concrete, however the assembly or utilization of such concrete needs minimum quantity of energy and causes least hurt to atmosphere. This kind of concrete absorbs the waste product that is additionally useful for atmosphere aspects [1]. Some SCMs area unit ash, oxide fume, ground coarse furnace scum, and rice husk ash. Fly ash materials area unit will be used as by partly substituting cement or sand; so, the business waste will be additionally used for aggregates in new construction. In the present research work, there are two different grades of conventional concrete which are M-25. Fly ash is used in both grades of concrete using steel fibres [2]. Fly ash is used in 20 and 30% from the replacement of the cement. Steel fibres are also added in the concrete as variation of 1, 1.5 and 2%. Finally, slump cone tests were performed on the concrete mix to check the slump value. Compression tests were performed on the concrete cubes after 7, 14, and 28 days to compare the results. Based on the test results, the influences of fly ash and steel fibre were investigated. The test results such as the compressive strength of fly ash steel fibre concrete obtained at 20 and 30% replacement cement with fly ash and addition of steel fibres at 1% is optimum among all the replacements of fly ash with steel fibres (1, 1.5 and 2%).
