Bhubaneshwar: Dalmia Bharat Cement showcased its much talked about Composite Cement at the recently concluded first summer school on low clinker green cement-based composites organised by Indian Institute of Technology, Bhubaneswar at its Argul campus. Composite Cement from the stable of Dalmia Group is a cement produced by inter-grinding of Clinker, Granulated Slag, Fly Ash and Gypsum at different proportions. It is expected to help enhance sustainability of cement industry by reducing clinker factor by utilizing industrial by products material such as fly ash and slag.
The training program-cum-workshop which witnessed participation of eminent academicians including Prof Victor C Li of University of Michigan and Prof. RabindraGettu of IIT Madras, aimed at bringing research and technological advancements in the field of green cement to lime light. Dalmia Bharat Cement, considered as one of the greenest cement companies by achieving lowest carbon footprint associated with cement manufacturing, remained a key player and leading sponsor for the cause.
Green cement-based composites are a class of materials that are also referred to as ‘bendable concrete’. Unlike ordinary concrete, these high-performance materials exhibit metal like ductility through a process known as pseudo-strain hardening which is accompanied by formation of multiple micro-cracks under load. These composites are developed based on performance-based design approach using micromechanics of fiber-matrix interaction. They are presently used in many applications ranging from high rise earth-quake resistant buildings to link slabs used on bridge pavements.
Talking about Dalmia Bharat Cement’s Green Cement, representatives of the Company at the Seminar said, “We at Dalmia Bharat Cement promote Innovation through our Green Cement, since we believe in adopting the best Industry practises and encourage an overall development in this market segment. This is part of our future roadmap to make a difference in the cement industry.”
The following advantages associated with Composite Cement can help in overall growth of the Industry and reduce the carbon footprint generated every year.
Composite cement provides multiple benefits due to use of both fly ash and slag as the single product covers a broad spectrum of applications both for mortar and concrete applications. From the trial already conducted at Dalmia Cement, based on inter-grinding, it has been found that there are multiple options available to manufacture composite cement by different combinations.
Dr. Prashant Kumar Panigrahy, Sr. General Manager – Quality Control (East), Shakun Vaidya, Head – Technical Services (East), Tushar Mohapatra, Sr. Manager – Technical Services and Rajanikanta Sarangi, Manager – Technical Services represented Dalmia Bharat Cement at the seminar.
