Development and testing of an advanced low-carbon concrete to significantly improve the sustainability of UK construction

Novacem是一种基于镁化合物的新型水泥，不需要原材料脱碳。它可以消除水泥生产中的二氧化碳（CO2）排放，并有可能超越碳中和，吸收二氧化碳，实现负碳生产。它有可能成为波特兰水泥（PC）的广泛替代品。PC制造业从能源使用和石灰石脱碳中释放约0.8吨二氧化碳/吨水泥。在英国，每年有超过1000万吨PC用于生产混凝土。全球每年使用近30亿吨（到2030年将达到50亿吨），产生5%的人为二氧化碳。如果要将Novacem用于主流建筑应用，首先必须充分展示Novacem混凝土的性能。该项目将改进Novacem的水泥成分，使用BRE的材料测试能力在标准测试中评估水泥性能，并使用Laing O 'Rourke的设施进一步展示性能。它将建立在TSB之前成功的合作研发项目的基础上，该项目突出了Novacem技术的潜力。

Novacem is a novel cement based on magnesium compounds that does not require raw material decarbonation. It could eliminate carbon dioxide (CO2) emissions from cement production, and can potentially go beyond carbon neutral to absorb carbon dioxide and achieve carbon negative production. It has the potential to become a widespread replacement for Portland cement (PC). PC manufacture releases approximately 0.8 tonnes of CO2 per tonne of cement from energy use and limestone decarbonation. Over 10m tonnes of PC are used to produce concrete each year in the UK. Globally almost 3bn tonnes are used each year (5bn tonnes by 2030), creating 5 percent of man-made CO2). If Novacem is to be used in mainstream construction applications, it is essential that performance of Novacem concrete is first well demonstrated. This project will improve Novacem’s cement composition, use BRE’s material testing capabilities to assess cement performance in standard tests, and use Laing O’Rourke’s facilities to further demonstrate performance. It will build on a successful prior TSB collaborative R&D project which highlighted the potential in the Novacem technology.
