Canada: Lehigh Hanson has launched of EcoCem Plus at its Edmonton cement plant in Alberta. The product is a blended Portland Limestone Cement (PLC) made using inter-grinding clinker, fly ash, limestone and gypsum. It is available in Alberta, Saskatchewan and Manitoba. The subsidiary of Germany-based HeildebergCement says it provides strength and durability while reducing the carbon footprint of concrete.

“The motivation behind the EcoCem brand of products is to reduce the embodied carbon of cement and concrete,” said Shawn McMillan, Vice President, Cement for Lehigh Hanson’s Canada Region. “The introduction of EcoCem Plus to the Prairie market builds on our commitment to providing environmentally responsible types of cement that deliver excellent performance while dramatically reducing CO2 emissions.”

Lehigh Cement has also published product and plant-specific environmental product declarations (EPD) for all of its cement products produced at its Edmonton plant.

US: The Portland Cement Association has launched greenercement.com, an informative website site dedicated to Portland Limestone Cement (PLC) applications and benefits. The organisation says that PLC’s 10% reduced carbon dioxide (CO₂) emissions when compared with Ordinary Portland Cement (OPC) make it the sustainable choice for innovative construction.

President and chief executive officer (CEO) Mike Ireland said, “PLC is another example of the cement industry evolving over the years, continuing to innovate and sustainably producing the high-quality cement that is needed to help keep America’s infrastructure strong and resilient.” He added, “This initiative will help educate engineers and other specifiers on how PLC can easily be incorporated into numerous projects.”

US: LafargeHolcim subsidiary Holcim US has rebranded its blended cement and supplementary cementitious materials range as Envirocore. Envirocore products include OneCem Portland limestone cement, MaxCem blended cement and NewCem slag cement.

The company noted that the partial substitution of cement with supplementary cementitious materials “not only results in more durable, high-performance concrete, but also lowers energy consumption and greenhouse gas emissions. CO₂ emissions are reduced by approximately 800,000kg/t of clinker replaced.” It also called on consumers to “adopt solutions that lower carbon emissions.”

Malaysia: Cahya Mata Sarawak (CMS) has launched a new Portland Limestone Cement (PLC) product. The 32.5N strength product is targeted for low-rise concrete structures such as single storey residential, office and commercial buildings. It is also intended for plastering, bricklaying and for use in the construction of drains and rural or kampong roads. CMS has also been conducting trials with Universiti Malaysia Sarawak (UNIMAS) on testing it as a binder for soil stabilisation. The new cement type will compliment CMS’ existing Portland Cement 42.5N product.

CMS operates one integrated cement plant and two grinding plants. Both grinding plants, at Pending in Kuching and Bintulu, have direct access to ports allowing entry to export markets for bagged and bulk product. The state-owned cement producer also operates two bulk marine terminals at Sibu and Miri.
