New Zealand: Neocrete has entered a partnership with major cement manufacturers, including Cemex, Heidelberg Materials, CRH, Titan, Cementos Argos and Ultratech Cement to promote its new Activator product aimed at reducing the amount of cement required in concrete. The product uses volcanic ash or residual ash from industrial processes to cut the amount of cement required by 40% to 50%, according to the company. Neocrete aims to replace cement completely, resulting in carbon-free concrete, by 2027. The new product will be submitted for life cycle assessment once a new pilot plant in Mt Wellington is operational. The plant is valued at US$2m and will produce 0.12Mt/yr of cement, to meet 10% of New Zealand’s demand.
Co-founder Zarina Bazoeva said "We don't need to produce the whole volume of cement. We activate the concrete chemically with a small catalyst at 3kg compared to 100kg of cement. So, we can scale fast."
