Admixtures And Special Concretes
Prof. Manu Santhanam · IIT Madras
About
The course – Admixtures and Special Concretes – builds upon the basics of construction materials and concrete technology to introduce the learner to the mechanisms of action of chemical and mineral admixtures and their impact on the performance of concrete. It goes on to introduce the students to the formulation and properties of special concretes that are increasingly being used nowadays in construction.
Intended audience: Senior UG students, PG and PhD students, Concrete Technologists, Practicing Civil Engineers
Prerequisites: Basic course in Construction Materials and preferably, Concrete Technology
