Cemex UK launches Vertua reduced-CO2 mortars

Written by Global Cement staff
01 August 2023

UK: Cemex UK says that it has achieved a 30% reduction in the CO2 emissions of its mortars range, enabling it to bear the company's Vertua sustainability label. The producer said that it has incorporated its Vertua CEM II A-L Portland limestone cement (PLC), alongside new admixture technology, in its mortar mixes. It added that it has upgraded drying processes in its mortar production, increasing energy efficiency.

Cemex's Europe regional mortars production manager Andy Bright said “By utilising designed mortar formations, we have been able to make a considerable carbon reduction to the products in our mortars range. These products are prized by our customers because of their strong performance and strength, flexibility of supply and wide range of colours and we are confident they will appreciate the opportunity to choose a more sustainable product too.”

Renca supplies zero-cement geopolymer mortar for 3D printing project in the US

Written by Global Concrete staff
24 July 2023

US: Geopolymer cement and concrete producer Renca has supplied its geopolymer 3D printing mortar for the construction of a house in the Western US. The product contains no cement, lime or gypsum due to the non-hydraulic binding properties of the mortar. It contains industrial by-products and has a faster setting time than mortar produced with ordinary Portland cement (OPC), as well as 90% lower CO2 emissions.

Renca said that its geopolymer mortar performed well despite the desert setting of the project, with dramatic changes in temperature. It added, "Even though geopolymer mortars require a specific approach towards the mixing procedure and, unlike cementitious-based products, need to be mixed in a batch mixing system, this milestone opens new horizons. Renca's current research and development seeks to develop a one-component geopolymer mortar for continuous mixers, as well as a 2K system where you can control the setting time right at the nozzle."

Global Cement and Concrete Association and WAP Sustainability launch environmental product declarations for concrete

Written by Global Concrete staff
18 July 2023

North America: The Global Cement and Concrete Association (GCCA) has partnered with consultancy WAP Sustainability to launch an on-demand environmental product declaration (EPD) service for concrete products. The partners say that their EPDs will allow concrete producers to show the impacts of their products across metrics including CO2 emissions. This is in line with current market trends, including increasing Buy Clean initiatives in federal and state procurement under the Inflation Reduction Act.

GCCA's concrete and sustainable construction director Andrew Minson said “The cement and concrete sector is playing a key part in sustainable construction, but this requires transparent, objective and accessible data on the environmental impact of our products. Our collaboration with WAP will allow concrete producers to quickly and cost effectively produce EPDs that can demonstrate the contribution of their products to a sustainable world of tomorrow.”

WAP Sustainability’s EPD director James Salazar said “WAP’s partnership with the GCCA leverages the GCCA’s industry-leading computation engine with WAP’s easy-to-use software and full-service support. As requirements for EPDs grow, we’re excited to offer credible and low-cost solutions through close partnerships with industry leaders like the GCCA.”
