Practical Concrete Mix Design

Avijit Chaubey completed his civil engineering from REC Durgapur (NIT Durgapur) in 1999. He has worked in various capacities from site engineer to heading the R&D division of concrete and cement manufacturing companies. During his professional tenure, he has been instrumental in implementing new technologies and materials in construction, which led to more sustainable initiatives in the construction industry that was facing an immense shortage of raw materials due to sustainability issues.

His major experience and contributions are in (i) hydro power projects, fast track construction projects, ready mix concrete industries; (ii) implementation of India’s second rollercompacted concrete technology for construction of dam; (iii) construction ofa hotel in record time, by designing fast-strength gaining concrete to speed up construction; (iv) first implementation of crushed rock fines to replace river sand for concrete manufacture in major cities of India for structural purposes; (v) developing a concrete road that could be trafficked within 24 hours of laying; (vi) ultra-lightweight concrete with a density less than water (lighter than water); (vii) acid-resistant concrete that could withstand attack even from sulphuric acid; (viii) developed a test method for ultimate shrinkage measurement in concrete; (ix) developed a mathematical model for void prediction in a mixture of solids; (x) optimization of concrete to get maximum profits through methodologies developed, which is also discussed in this book (this also led to a reduction in cement consumption for manufacturing concrete for the same strength and properties of concrete).

Avijit has published few papers in reputed journals and magazines, one of his papers under the guidance of Dr Amlan Das (Prof NIT Durgapur), “Design of Parabolic Channels” won an award from Union Ministry of Water Resources in 2001. Avijit has served in organizations like Shapoorji Pallonji, Gammon India, and ACC Concrete and is currently working with Ultratech Cement.
