Effect of Cupola Slag as a Partial Replacement of Coarse Aggregate on Mechanical Properties of Geopolymer

This project represent the study on properties of Geo-polymer concrete with various mixes in which coarse aggregate is replaced with by-product of CI industries (cupola slag). In this study Geo-polymer concrete produced with Sodium-hydroxide (NaOH ) and Sodium-silicate (Na2.SiO3)as a alkaline solutions for chemical activation of binder, 12 Molarity of alkaline solution is also taken in this study. Cement replaced by GGBS (Ground Granulated Blast Furnace) (30%) and Fly Ash (70%) to decreases the usage of cement. Main objective of this project is to investigate for changes in mechanical properties of concrete with the use of cupola slag in varying percentage which is suitable for construction with higher durability and higher flexural strength. In this study attempt cupola slag is used as alternative of natural coarse aggregate and cube will be made up with 10% of CSA with 90 % NCA to 50 % of CSA with 50% NCA with increment interval of 10% of Cupola content for the testing of durability (acid attack) and flexural strength.
