The basic course on Civil Engineering Materials deals with some fundamentals related to concrete and concrete materials, besides dealing with masonry, steel etc.
The specific course on "Concrete Technology" focuses more on detailed understanding of concrete making materials including supplementary cementitious materials.
Concrete production process also forms a part of the discussion. Recent developments in concrete materials are also given adequate consideration.
Going through the course one would develop adequate understanding on concrete production process and properties and uses of concrete as a modern material of construction.
The courses will enable one to make appropriate decision regarding ingredient selection and use of concrete.
Contents:
