Experimental Investigation on Partially Replacement of Cement and Fine Aggregate by Glass Powder and Vermiculite
Concrete is the most widely used manmade material in the construction industry. So, it is essential to utilize industrial by - products and waste products instead of concrete, which has many advantages. Waste glass from glass manufacturing industries can be grounded and used as an alternative for cement. Glass has high silica content, thus making it potentially pozzolanic. Finely ground glass does not contribute much to alkali - silica reaction, which can be prevented by adding mineral admixtures. Vermiculite is a low density material obtained by exfoliating rock. It can be used as replacement for fine aggregate because of it’s specific properties such as light weight, improved workability, fire resistance. This project work aims at studying the effects of replacing cement and fine aggregate by glass powder and vermiculite respectively in M35 grade concrete. Vermiculite is added in 12 %, 15 % and 18 % of fine aggregate and glass powder is added in 15 %, 18 % and 20 % of cement. The main objective is to analyse compression, splitting tensile and flexural strengths for various proportions of vermiculite and glass powder are compared with conventional specimens.
