Abstract

The advancementof concrete technology can reduce the consumption of natural resources and energy sources and lessen the burden of pollutants on environment. Presently large amounts of fly ash and glass powder are generated in thermal and glass industries with an important impact on environment and humans. In recent years, many researchers have established that the use of supplementary cementitious materials (SCMs) like glass powder, fly ash (FA), blast furnace slag, silica fume, and rice husk ash (RHA), etc. can, not only improve the various properties of concrete - both in its fresh and hardened state, but also can contribute to economy in construction costs. This research work describes the feasibility of using such industrial waste in concrete production as partial replacement of cement. The use of glass powder and fly ash in concrete formulations as a supplementary cementatious material was tested as an alternative to traditional concrete. The cement has been replaced by glass powder and fly ash accordingly in the range of 0% (without fly ash), 10%, 20%, 30% & 40% by weight of cement for M-25 mix. Concrete mixtures were produced, tested and compared in terms of compressive and split strength with the conventional concrete. These tests were carried out to evaluate the mechanical properties for the test results for compressive strength up to 21 and 28 days. The aim of the present work was to replace cement by glass powder and fly ash as a admixture to assess the pozzolanic activity in concrete and compare its performance with plain concrete. It was found that compressive and tensile strength of the concretes increased as fineness increased. It was concluded that fineness of fly ash have positive impact on mechanical properties of concrete and cement motar.
