Reliance Power, which runs a 1,200-MW thermal power plant in Shahjahanpur district. The Rae Barel i cement plant production would be able to bridge the demand supply gap in UP. The cement market in the state is likely to grow six per cent per annum in the near future. Courtesy: The Indian Cement Review, April 2014 Pg. No. 14 Merger & Acquisition JAYPEE GROUP MAY HIVE OFF PANIPAT CEMENT UNIT The Manoj Gaur led Jaypee Group plans to hive off its cement grinding plant based at Panipat CALCIUM FREE CONCRETE INVENTED Cement as we know, has large amount of calcium compounds in it. Whi le in normal conditions this is not an issue, problems start surfacing when it comes to construction in corrosive soils, like in the Middle East. Middle Eastern soils are high in sulphate and chlorides, which attack the calcium in the cement. Construction in such areas is a big challenge. The Wagner fami ly from Toowoomba have now perfected a calcium- free cement mix, which is inherently immune to corrosive deterioration. After eight years of research for perfecting the concrete without Portland cement , the product is now ready for its commercial sale. The new mix in the state of Haryana. The valuation of this unit is pegged at Rs 400 crore. Swiss construction giant Holcim has a majority ownership of ACC and Ambuja Cement. The combined capacity of Holcim in India is about 52 million tonnes. It is learnt from news reports that Holcim is in the race to buy Jaypee Group cement unit at Panipat. Jaypee Group plans to reduce its debt burden by Rs 15,000 crore by the end of the current fiscal. The company has a total debt of about Rs 60,000 crore.

Trials on pre-cast tunnel segments of the Wagners' earth friendly concrete (EFC), as they call it, have been completed in Malaysia and, last week, at Doha in Qatar. The concrete uses fly ash and slag, recycled from steel making and coal– fired power stations, is combined with chemical activators to create a geopolymer binder. EFC does not need added protection from corros1on, and its flexural strength and low shrinkage makes it perfect for underground tunnels. Courtesy. The Indian Cement Review, April 2014 Pg. No. 22 Energy Efficiency & ·Conservation Energy Conservation ~· ACC PLANS WASTE-HEAT RECOVERY SYSTEM AT FOUR PLANTS After commissioning its first waste-heat recovery plant at Gagal in Himachal Pradesh , ACC plans to replicate the success at its cement plants m Wadi (Karnataka), Jamul (Chhattisgarh), Kymore (Madhya Pradesh) and Chanda (Maharashtra) with an investment of about ~ 360 crore . The Gagal heat recovery plant, which produces 7.5 MW. achieved stabilization last week. It is expected to reduce over 44,000 tonnes of carbon-dioxide emission a year Gagal . faces shortage of power during winter, as hydro-power plants taper off generation due to snowing. ACC invested ~ 100 crore to set up the plant which is fitted with a turbine that can enhance power production to 9 MW as and when steam availability in the cement plant improves. ACC expects to recover the investment made in Gagal in four-and-a-half years with an annual saving of ~ 22 crore. K.N. Rao, Director (Energy and Environment). told Business Line the four cement plants where the heat recovery system would be instal led over 3-4 years are capable of producing 30-32 MW in all , resulting in a savings of~ 90-1 00 crore a year ''h.' - '
