Mineral Admixtures: Strength Activity Test, Lime Reactivity Test, Mixture Proportioning and R3 Test

Learn about various methods for measuring pozzolanic activity in mineral admixtures through this 20-minute video lecture. Explore the electrical conductivity method, Frattini test procedure, lime saturation method, strength activity test, and lime reactivity test in detail. Discover the R3 test method, which combines multiple techniques to assess pozzolanic activity. Gain insights into the crucial aspects of mixture proportioning using Supplementary Cementitious Materials (SCMs). This comprehensive lecture from NPTEL-NOC IITM covers essential topics for understanding mineral admixtures and their applications in concrete technology.
