Determination of Mechanical Properties of Mortar by Using Fine Crushed Glass (FCG) and Waste Rubber (WR)

Abstract

Concrete contain more amount of cement which will release more CO2 and effects the environment, therefore to reduce the amount of cement in a concrete one should have approach towards replacement of cement with other waste and cost effective material such as glass. Since waste glass is not biodegradable and therefore alternative usage of it is required. Such can be used as coarse aggregate and substitute of cement constituents in concrete and mortar. Also disposal of waste glass into landfills is one of the major issues that have been come across. This study aims on reducing such problems by the usage of waste glass as one of the replacing material in cement mortar. The pozzolanic activity of glass powder and properties of glass powder blended cement were evaluated. Also the mechanical and chemical properties of such blended mortar has been evaluated. The cement is replaced 0%, 5%, 10%, 15% and 20% by glass powder content by weight of cement. The test results shows that on adding the optimum amount of waste glass the compressive strength of mortar has been increased. Also at 5% replacement of cement with waste glass powder gives the best proportion to increase compressive strength and reduce the cost of conventional mortar.
