Manufacturing processes for concretes using Portland cement (PC) are well established and account for 5-8% of global man-made CO2. End users of concrete products now demand low environmental impacts. However, reducing these impacts whilst still meeting user requirements (product performance and volume) remains a major challenge for the industry in the UK & globally. The project will address this challenge by developing and scaling up new manufacturing processes and implementing materials innovation to enable the cost effective production of low CO2 concrete products from alternative binders to PC based on waste or byproduct materials that harden by a chemical activation. The project will also assess the use of reclaimed materials (e.g. landfilled pfa) without use of conventional PC and as a partial replacement for PC in conventional concrete. It will thus address manufacturing challenges and broaden the scope of materials inputs & end user segments to create solutions scalable by UK SMEs and support them to develop new services for a large market.

使用波特兰水泥（PC）的混凝土制造工艺已经成熟，占全球人造CO2的5-8%。混凝土产品的最终用户现在要求低环境影响。然而，在满足用户要求（产品性能和数量）的同时减少这些影响仍然是英国和全球行业面临的主要挑战。该项目将通过开发和扩大新的制造工艺和实施材料创新来应对这一挑战，以实现低二氧化碳混凝土产品的成本效益生产，从替代粘合剂到基于废物或副产品材料的PC，通过化学活化硬化。该项目还将评估在不使用传统PC的情况下使用回收材料（例如填埋的PFA），并作为传统混凝土中PC的部分替代品。因此，它将解决制造业的挑战，扩大材料投入和最终用户细分的范围，以创建可由英国中小企业扩展的解决方案，并支持他们为大型市场开发新服务。
