Brazil: Gerdau Graphene has launched NanoCONS, a new line of graphene-based admixtures for concrete. Graphene-Info News has reported that NanoCONS increases the durability and strength of concrete, while lowering its CO₂ emissions by 20%, according to the developer. Gerdau Graphene noted that the first product in the line, water-based NanoCONS W104, offers faster drying times, making it well-suited to use in precast concrete production.

US: Premier Graphene has despatched test samples of its proprietary graphene suspension to ‘one of the largest essential materials companies.’ Graphene-Info News has reported that Premier Graphene expects the samples to confirm its findings of a 32% increase in compressive strength after 28 days, compared to concrete produced without its graphene.

President Pedro Mendez said "Our internal tests have confirmed multiple advantages that position our green cement product strongly in the market. These include increased strength with reduced cement usage, substantial carbon footprint reduction and enhanced durability. We anticipate strong market adoption driven by our cost-effective graphene production methods and established, remarkable efficacy. Our strategy encompasses both graphene colloids for customised mixing by manufacturers and the development of graphene-based products like epoxies and lubricants. This phased approach minimises capital expenditure while maximising product innovation.”

Spain: CRH’s Catalonian ready-mix concrete subsidiary Beton Catalan has partnered with Grapheno Smart Materials in order to implement the latter’s graphene technology in its high-performance concrete products.

Beton Catalan’s quality director Alberto Arenillas said that the company’s high-performance concrete products require ‘a significant amount of CEM I cement,’ He said “By introducing the graphene additive, the nominal amounts of this cement can be reduced or changed to cement with a lower carbon footprint, improving its performance.” The company will sell the graphene-enriched concrete under its BeGreen reduced-CO₂ products label.

UK: Concrene Limited has obtained a US patent for its Graphene Reinforced Concrete technology. The technology uses graphene dispersed in water to create a uniform distribution of graphene particles in concrete. Graphene increases the strength of concrete, enabling less cement to be used in its production.

Concrene Limited invited interested US stakeholders to discuss opportunities for commercial partnerships.
