New Blended Cements


NEW  BLENDED  CEMENTS
Paper Presented 
at
INDIAN CEMENT REVIEW CONFERENCE 2014 ON SUSTAINABILITY IN INDIAN CEMENT INDUSTRY
6 JUNE 2014, MUMBAI, INDIA



 In India, majority of cement produced is of blended variety, with fly ash and blast furnace slag as the mineral admixtures used for blending. Blended cements production reduces clinker production thereby leading to conservation of natural resources and energy and also substantial reduction in the CO2 generation, which is a green house gas. The production of blended cements also leads to utilization of two major industrial wastes, coming from thermal power stations and the integrated steel plants. The application of blended cement in concrete imparts better strength and durability properties to the structure. Keeping these aspects in mind, the presentation illustrates the characteristics of two varieties of blended cements, new to Indian cement industry, namely Portland Limestone Cement (PLC) and Portland High Volume fly Ash Cement (PHFC).

The conference was attended by prominent figures from the cement and construction industry. The major organisations represented were: Cement Manufacturers' Association (CMA), Reliance Cement, World Business council for Sustainable Development (WBCSD), Ambuja Cement, ACC, Siemens, Allan Smith, Thermax.
