Recently, the 16th NCB international seminar on Cement, Concrete and Building Materials during December 3-6, 2019 at Zorawar Auditorium, Manekshaw Centre, New Delhi was successfully organised under the leadership of Dr BN Mohapatra. The seminar with the theme of "Clean & Green is sustainable" focused on important and relevant topics related to cement and construction industry. More than 190 technical papers were deliberated spread over 23 technical sessions and one student session during the seminar.
NCB seminar provided a common platform for sharing of knowledge between cement industries, academicians, research scientists, equipment manufacturers, government agencies and experts from cement and construction industry.
For the first time in NCB seminar, two panel discussions were held with participation of the leaders of Indian cement industry and other distinguished panellists from government agencies and industry bodies. The first panel discussion on "Changing Climate - A threat or opportunity to cement industry" saw new ideas and perspectives on the issue. We have covered it separately in more detail in the current issue. Overall, the findings of panel discussion is that Indian cement industry considers the threat of climate change as opportunity and is constantly making efforts to minimise the impacts of climate change from cement production. The second panel discussion was on the topic "Cement and construction industry-A convergence point of circular economy".
Three keynote presentations were made by eminent scientists on various topics such as"Emerging Technological Options for Improving the Application Potential of Blended Cements" by Dr AK Chatterjee, "Sustainability Assessment of Concrete systems with alternate binders" by Dr Ravindra Gettu and "Smart Cement Based Composites - A review" by Dr Dhanada K Mishra.
The session on raw materials resource management saw papers presented on use of High MgO and high phosphate limestone and conservation of limestone reserves by cement plants. The two sessions on Portland, blended and special cements saw papers presented on high MgO clinker for Blended cements, composite cement, Portland limestone cement, increased utilisation of fly ash in PPC by cement plants. The session on alternate/waste fuels and raw materials saw papers presented on AFR handling systems and usage of waste materials like leather sludge, LD slag, and egg shell in cement manufacture.
The two sessions on advances in grinding systems saw papers presented by OEMs on optimisation of grinding process, latest development and experiences on roller press and VRMs at cement plants. The session on Cement Plant Machinery and Project Engineering saw papers presented by OEMs on new development in coolers, APCE and upgradation and improvements by cement plants.
The two sessions on energy management systems saw a range of papers presented on measures like energy efficient coolers, reduction in thermal energy, improvement in energy efficiency, energy audits, waste heat recovery adopted by cement plants as well as provided by the suppliers. The three sessions on environment management and sustainability saw papers presented on NOx mitigation measures adopted by various cement plants including primary measures and secondary control techniques like SNCR, papers were presented on SO2 control techniques for captive power plants, dust control techniques for control of point source as well as fugitive emissions and papers were also presented on the sustainability measures including reduction of CO2 emissions, water conservation measures taken by cement plants.
The technical exhibition was formally inaugurated immediately after the kickstart of seminar at Zorawar Auditorium at the hands of Chief Guest Guruprasad Mohapatra, Secretary, DPIIT, Ministry of Commerce and Industry, Government of India. In all there were more than 70 exhibitors from India and abroad some of whom had even a display of the products/systems at the venue. The exhibition could provide a platform for the equipment manufacturers, service providers to meet their old customers and new ones. Some of the equipment manufacturers have been participating regularly and did not show any sign of economic slowdown.
