Abstract:

The alteration in quantities for preparing sundry concrete mix has been a great challenge for the concrete industry. The present work investigates replacement of sand and cement with glass powder (GP) and fly ash (FA) respectively. GP being rich in silica has the potential to replace sand as fine aggregate in concrete. The propensity of using FA as a supplementary cementitious material was done to improve the properties of concrete that utilized finely crushed waste GP, especially with regards to inhibit the alkali-silica reaction (ASR). This proportionate replacement of sand with GP can possibly solve the ongoing crisis of sand procurement through mining which is a direct cause of erosion. The term environmental economics has been used to analyse the burgeoning effects on nature and to alleviate the increasing cost of construction. The GP was used in proportions of 0%, 5%, 10%, 15% and 20% as a fine aggregate replacement. An experimental study was made where compression strength, flexural strength, tensile strength and modulus of elasticity of proportioned concrete mixes were examined and compared. Therefore viable improvisation can be done by using FA and GP as binders to make an efficacious concrete.
