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.

国家统计局估计，英国的建筑部门占GDP的6.1％。水泥和混凝土生产是大多数施工过程的重要贡献者，因此对于创造就业机会至关重要。水泥子部门在整个制造业和180亿英镑的矿物产品领域均独特地削减，除350万间接工作外，还直接雇用了74,000名员工。该部门对国家和全球发展的影响很有价值，它对能源消耗的影响（探索了能源的60-70％的水泥生产成本），温室气体排放量很大。例如，英国建筑行业的排放在2019年为1300万吨，自1990年以来一直在不断增加。同样，归因于英国水泥制造活动的温室气体排放量已从2007年的320万吨悄悄地增加到2019年的440万吨。随着当前的全球推动对能源效率的更严格的立法，基金会行业的可持续性和可持续性，例如水泥将在很大程度上取决于他们降低能源消耗和碳足迹的程度。尽管目前在水泥行业中探讨了包括碳捕获技术在内的几项计划，但与技术复杂性和成本影响有关的问题仍在持续。因此，目前的项目将探索石墨烯在建筑部门及其相关的供应链中的应用（尤其是水泥制造），以提高能效，原材料优化和水泥/混凝土的整体性能。基本研究已经描述了石墨烯能够显着增强混凝土强度，但主要侧重于用户最终（例如，构造站点），而不是在建筑站点上进行工具。由于每个重量所需的石墨烯量的微量量，因此尚未研究石墨烯注射和分散大量石墨烯的问题。因此，我们将旨在开发一种新型的“高性能石墨烯增强水泥”（GR-CEM）产品。 GR-CEM将提供机会使用较低等级的水泥制造原材料（例如，在燃烧/低温熟料，原始石灰石等下），因此有助于减轻水泥制造的碳影响。因此，该项目将考虑到优化的石墨烯分散和注入系统的开发，GR-CEM的经济可行性及其碳以及健康与安全影响。
