Admixtures in Concrete | Plasticizers, Accelerator etc... | Quality of Water used for Concrete

Admixtures in Concrete: Chemical & Mineral | Building Materials ​Welcome back to CIVIL GYAN CENTER! In today’s session, we dive deep into one of the most crucial topics of Building Materials and Construction (BMC): Admixtures. ​Understanding how to manipulate the properties of concrete is essential for any Civil Engineer. Whether you are preparing for SSC JE, RRB JE, ESE, GATE, or UPPSC Polytechnic Lecturer exams, this video covers everything you need to know about Chemical and Mineral admixtures with a focus on previous year exam patterns. ​📝 What You Will Learn: ​In this video, Shree Vardhan Srivastava explains: ​Introduction to Admixtures: Why do we use them and what are the IS Code specifications? ​Chemical Admixtures: ​Plasticizers & Super-Plasticizers: Increasing workability without adding extra water. ​Retarders: Delaying the setting time (perfect for hot weather concreting). ​Accelerators: Speeding up the setting time (essential for cold weather or urgent repairs). ​Air-Entraining Agents: Improving freeze-thaw resistance. ​Mineral Admixtures: * The role of Fly Ash, Silica Fume, Metakaolin, and GGBS in enhancing durability and strength. ​🚀 Target Exams: ​🎯 SSC JE / RRB JE 🎯 ESE (Engineering Services Examination) 🎯 GATE (Civil Engineering) 🎯 UPPSC / State PSC AE & JE 🎯 Polytechnic Lecturer Exams ​📢 Join Our Community: ​If you found this video helpful, please Subscribe to CIVIL GYAN CENTER and hit the bell icon 🔔 to never miss a technical update!
