The Office of National Statistics estimates that the UK's construction sector accounts for 6.1% of GDP. Cement and concrete production are significant contributors to most construction processes, thereby making it very crucial for job creation. The cement subsector uniquely cuts across the manufacturing and £18bn-GDP Mineral Products sector that directly employs 74,000 people in addition to 3.5m indirect jobs. As valuable as the impact of this sector is to national and global development, its impact on energy consumption (60-70% of cement production cost is expended on energy) and greenhouse gas emissions is immense. For instance, the emission from the UK's construction industry was 13 million metric tonnes in 2019 and has continuously increased since 1990\. Similarly, greenhouse gas emissions attributable to UK's cement manufacturing activities have steadily risen from 3.2 million metric tonnes in 2007 to 4.4 million metric tonnes in 2019\. With the current global push for more stringent legislations on energy efficiency, the profitability as well as sustainability of foundation industries, such as cement would significantly depend on how much they lower their energy consumption and carbon footprints. While several initiatives including carbon capturing technologies are currently explored within the cement industry, questions related to technical complexity and cost implications still linger. Therefore, the current project will explore the application of graphene within the construction sector and its associated supply chain (especially cement manufacturing), to improve energy efficiency, raw material optimisation and the overall performance of cement/concrete.Preliminary investigations have already depicted the ability of graphene to significantly enhance concrete strength, but such studies mainly focused on the user end (e.g., construction sites) and less on the cement manufacturing process. Owing to the minute quantity of graphene required per weight, the issues surrounding the injection and dispersion of graphene within large quantities of cement have also not been investigated. Therefore, we will aim to develop a novel "high performance Graphene Enhanced cement" (GR-CEM) product. The GR-CEM will offer the opportunity to use lower grades of cement manufacturing raw materials (e.g., under burnt/low temperature clinker, raw limestone, etc.) and therefore contributing to mitigating the carbon impacts from cement manufacturing. The project will thus take into account the development of an optimised graphene dispersion and injection system, the economic viability of GR-CEM as well as its carbon and health and safety impact.

英国国家统计局估计，水泥和混凝土生产占英国 GDP 的 6.1%，对大多数建筑流程做出了重要贡献，因此水泥行业对创造就业机会至关重要，占制造业的 180 亿英镑。 -GDP 矿产品行业直接雇用了 74,000 人，此外还提供了 350 万个间接就业机会，该行业对国家和全球发展的影响同样重要，它对能源消耗的影响也同样重要。 （水泥生产成本的 60-70% 消耗在能源上），温室气体排放量巨大，例如，2019 年英国建筑业的排放量为 1300 万吨，并且自 1990 年以来不断增加。在当前全球推动下，英国水泥制造活动的排放量已从 2007 年的 320 万吨稳步上升至 2019 年的 440 万吨。对于更严格的能源效率立法，水泥等基础行业的盈利能力和可持续性在很大程度上取决于其能源消耗和碳足迹的降低程度，而水泥行业目前正在探索包括碳捕获技术在内的多项举措。与技术复杂性和成本影响相关的问题仍然存在，因此，当前项目将探索石墨烯在建筑领域及其相关供应链（特别是水泥制造）中的应用，以提高能源效率、原材料优化和整体性能。水泥/混凝土的初步调查已经描述了石墨烯增强混凝土强度的能力，但此类研究主要集中在用户端（例如建筑工地），而较少关注水泥制造过程，因为单位重量所需的石墨烯数量极少，因此存在一些问题。石墨烯在大量水泥中的注入和分散尚未得到研究，因此，我们的目标是开发一种新型的“高性能石墨烯增强水泥”（GR-CEM）产品，GR-CEM 将提供使用机会。较低年级的水泥制造原材料（例如，烧成/低温熟料、生石灰石等），因此有助于减轻水泥制造的碳影响，因此该项目将考虑开发优化的石墨烯分散和注入系统， GR-CEM 的经济可行性及其碳、健康和安全影响。
