Concrete Technology

Dr. Amandeep Singh, Scientist ‘E’

The main activities of the Concrete Technology group are:

• Field and laboratory investigations of construction materials for major river valley projects in India and abroad. It has full-fledged field and laboratory facilities for conducting standardized (BIS, ASTM etc.,) and specialized testing and analysis of concrete, masonry, cement, supplementary cementitious materials (SCM), steel and other construction materials for evaluating the material properties, suggestions on non-fulfilling acceptance criterion and performance / compatibility problems.
• Special testing facilities, housed in concrete laboratory, are utilized for studying the thermal properties of mass concrete, Abrasion Erosion Resistance.
• Mix design of mass concrete, high performance concrete, self-compacting concrete, fibre reinforced concrete, plastic concrete etc.
• Construction quality control of concrete in the field for major hydraulic structures.
• Dissemination of expertise to in-service engineers of various State Government Departments, Centre/State PSUs for establishing regional testing laboratories and impart training on handling of equipment and testing of concrete & its ingredients.
• Disseminating knowledge on Roller Compacted Concrete for the construction of dams in the country.
• Quality Control/Assurance of Concrete Structures.
