CONSTRUCTION TECHNIQUES, EQUIPMENT AND PRACTICES
The main objective of this course is to make the student aware of the various construction techniques, practices and the equipment needed for different types of construction activities. At the end of this course the student shall have a reasonable knowledge about the various
construction procedures for sub to super structure and also the equipment needed for construction of various types of structures from foundation to super structure.
UNIT I CONCRETE TECHNOLOGY
