Metakaolin, Quarry dust, Compressive strength, Partial Replacement


The current experimental investigation focuses on the influence of Quarry residues and Metakaolin on the compressive strength of concrete. Sand is partially replaced with Quarry dust and cement by Metakaolin in M25 grade of concrete. The present experimentations reveal that Metakaolin can replace cement, and quarry dust can substitute fine sand in concrete to some extent. At 30% replacement of fine sand with Quarry dust, increase in compressive strength was noticed. Simultaneously, 8% replacement of cement with Metakaolin, displayed better compressive strength. The test results were found to be satisfactory with the individual replacements but the combination of Quarry dust and Metakaolin did not yield positive results with respect to compression of concrete.
