EXPERIMENTAL INVESTIGATION ON THE STRENGTH CHARACTERISTICS OF CONCRETE MADE WITH METAKAOLIN, FOUNDRY SAND AND DEMOLITION WASTE

Concrete had reached its increasing demand since the construction industry involved innovation in all forms of phenomenal infrastructural works. The main objective of our project lies in find a perfect solution for the diminishing resources of cement, fine and course aggregates. Our ideology was adding metakaolin, foundry sand and demolition waste to the concrete and studying the strength properties of concrete with the variation in nominal mix. i.e., to study the strength properties of concrete (M20 Grade) for mix ratio of 5%,10%,15%,20% and 25% at 7 and 28 days. The strength properties being studied in our theses are as follows: 1. Compressive strength 2. Split Tensile strength 3. Flexural strength These properties were then compared with the nominal concrete mix
