UK: England Notional Building Material Group Holding Group (ENBMGHG) has launched its new CEggMent binder for concrete. The binder is capable of replacing up to 100% of cement and aggregates in concrete. It is available in individual ovoid packages, which can be dropped into the concrete mixer. They consist of a calciferous ‘shell’ that breaks into hard shards and a fluid centre that allows CEggMent to fill any space into which it is poured.

ENBMGHG has launched the ConWheat range of additives to aid the forming and setting of CEggMent, including ConEmmer, ConSpelt and EinCon. All ConWheat additives are available as bagged powders, ground to a fineness of 900cm²/g ‘Grade 2’ to 1800cm²/g ‘Double-Zero.’

ENBMGHG says that CEggMent is available to order across England in multiples of six or for collection with payment by means of ‘honesty box’ in rural areas.

US: Cortec has unveiled a new logo for its MCI brand of corrosion inhibitors. The logo retains its predecessor version’s grey and green hexagon and slogan ‘From Grey to Green,’ with a new bold, black font for the MCI name.

MCI corrosion inhibitors work topically or as a concrete admixture to form a protective layer around metal structures in concrete.

US: Holcim US won a National Ready Mixed Concrete Association (NRMCA) Concrete Innovations Award for its contributions to the Lower Carbon Content Concrete Pavement MnROAD project in Minnesota. The producer supplied its reduced-CO₂ ECOPact ready-mix concrete.

Holcim US North Central Regional Senior Vice President and General Manager Randy Gaworski said "Our ECOPact low-carbon concrete mix included Portland limestone cement (PLC), slag cement, fly ash and other materials to reduce total cementitious materials, achieving a mix with less than 50% clinker content. This innovative approach demonstrates the ability to reduce carbon content in construction materials with no compromise on performance."

Holcim also received nominations for its supply of its Ductal Ultra-High Performance Concrete for the Delaware Memorial Bridge overlay project in Delaware/New Jersey and its supply of its Agileflow ultra-lightweight concrete mix for the Babcock Street Outfall Project in Buffalo, New York.

US: Researchers at Northwestern University have developed a carbon-negative building material using seawater, electricity and CO₂. The process mimics the development of mollusc shells and coral reefs, using electrical instead of metabolic energy, and injecting the necessary CO₂. Electrek News has reported that the resulting materials consist of a mix of carbonate and hydroxide minerals, including calcium carbonate.

Building materials producer Cemex reportedly contributed to the research.
