Description

Practical Concrete Mix Design has been compiled with an endeavour to help readers understand the concrete mix design methodology including formulas and tables involved in the pertinent steps. The book helps engineers to understand the mix design procedure, as the book contains every possible explanation for each step of mix design, limitations given by standards, and practical guide on tailor making of concrete for each different kind of requirement. It covers why, how, and when about the concrete proportioning and optimization. The book provides the necessary skills for the engineers to hone their skills in doing so, understanding the risks involved, and troubleshoot related problems.

About the Author

Avijit Chaubey completed his civil engineering from REC Durgapur (NIT Durgapur) in the year 1999. He has worked in various capacities from site engineer to Heading 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, which was facing immense shortage of certain type of aggregates.

His major contributions include: 1) Construction of Kol Dam- power house which used 100% replacement of river sand with crushed rock fines, 2) Implementation of Roller compacted concrete Dam in Teesta West Bengal, 3) Construction of a hotel in record time of 8 months, which was made possible by designing fast strength gaining concrete to speed up the construction, 4) First Implementation of crushed rock fines 100% to replace river sand in Pune, Mumbai and major cities of India for structural purpose, 5) Developing of a Concrete Road which can be trafficked within 24 hours of laying, 6) Ultra Light weight Concrete with a density less than that of water (lighter than water), 7) Zero Energy Mixer, which helped people to mix raw materials of concrete without any fuel or Electricity, 8) Acid Resistant Concrete which could withstand attack even from sulphuric Acid, 9) Developed a test method for ultimate shrinkage measurement in concrete, 10) Developed a mathematical model for void prediction in mixture of solids, 11) Optimized concretes to get maximum profits through methodologies developed by self, which has also been discussed in the book, this also led to reduction in cement consumption for manufacturing concrete for same strength and properties of concrete. Avijit has published few papers in reputed journals and magazines out of which One paper (Under Guidance of Dr. Amlan Das- Prof NIT Durgapur) won award from Union Ministry of water resources for a paper titled “Design of Parabolic Channels” in 2001. Avijit has served in organizations like Shapoorji Pallonji, Gammon India, ACC Concrete and is currently working with Ultratech Cement.
