Dirk was chairing the session with prominent speakers like Dr. P.C. Basu (Director Civil and Structural Engineering ,AERB . Mumbai), Dr. N.N. Som (former Professor of Civil Engineering of Jadavpur University, Kolkata), Mr. He Fu An (President, Committee of Nanjing Fly Ash Recycling Society, China), Prof. S. Saraswati, (Professor Construction and Engineering Departnment , Jadavpur University, Kolkata) and Mr. Kollol Basu (CEO of LYTAG, India).
In the lively discussion which followed the presentations it was marked again that trading of unprocessed fly ash is a threat to the industry. Mr. Dirk raised the controversial issue of comparing PPC with OPC/Fly Ash blends and the economical aspects of this. The plenum requested the Coal Ash Institute to lobby inside the Bureau of Indian Standards to have the permitted maximum Fly Ash/ OPC replacement rate of currently 35% increased to 40 or 45 %.
Mr. Dirk thanked the president of the Coal Ash Institute of India, Dr. A.K.Chatterjee, to make this valuable event possible.
