For all other env, poll & con 4th sem bteup diploma syllabus 2017 you can visit Env, Poll & Con 4th Sem BTEUP Diploma Syllabus 2017 Subjects. The detail syllabus for concrete technology is as follows.

Rationale:

Concrete Technology is very important subject for Civil Engg. Diploma holders students should have deep understanding of material principles and processes used in making and using the concrete.
This will help the student to supervise and control the quality of concreting operations in various situations. Demonstration, field visit and laboratory work should be so organised as to develop comprehension of subject in the students.
