　　Design Theory, Preparation Technique and Engineering Application of Low Carbon Blended Cement

　　【发言摘要】硬化水泥浆体中熟料与矿渣等辅助性胶凝材料水化程度低，胶凝材料未得到高效利用，造成了资源严重浪费。如何匹配熟料与辅助性胶凝材料粒度、水化等特性，是提高胶凝材料利用效能、大宗量利用废渣制备水泥必需解决的关键科学问题与技术瓶颈。该研究从浆体初始堆积和水化进程调控角度，提出了“区间窄分布，整体宽分布”颗粒级配模型，并根据颗粒表面非均匀水膜进行修正，显著提高了浆体初始堆积密度。为高效利用胶凝材料，高活性辅助性胶凝材料、水泥熟料、低活性辅助性胶凝材料或惰性填料应分别置于复合水泥的细、中、粗粒度区间，各胶凝组分可温和、梯级、持续水化，复合水泥浆体结构逐渐密实，仅采用25%熟料、70%工业废渣制备了42.5强度等级复合水泥。

　　The hydration degrees of cement clinker and supplementary cementitious materials (SCMs) in hardened cement paste are relatively low, which means both clinker and SCMs are not efficiently utilized. Therefore, how to match the particle size and hydration characteristics of clinker and SCMs becomes the key scientific issue and technical challenge in improving the utilization efficiency of cementitious materials. A gap-graded particle size distribution (PSD) model was proposed, and then modified by introducing a non-uniform water film coated on the surface of solid particles. The results show that cement with gap-graded PSD has higher wet packing density, thereby the amount of hydration products to fill the voids among solid particles is decreased. To efficiently utilize cement clinker and SCMs, high activity SCMs, cement clinker, low activity SCMs or inert fillers are suggested to be arranged in the fine, medium-size and coarse fractions of blended cement, respectively. As results, hydraulic components, including cement clinker particles and SCMs, hydrate continuously to densify the microstructure. Finally, blended cements with only 25% clinker and 70% solid wastes prepared can meet the requirements of 42.5 grade cement.

　　【发言主题】水泥行业CCUS发展：全球现状与前景展望

　　CCUS Development in Cement : Global Status and Outlook

　　【发言摘要】CCUS在GCCA净零路线图中具有重要地位，在行业脱碳中作用关键。推动CCUS规模化应用的核心要素，包括捕集技术的进步、运输与封存基础设施的建设需求，以及完善的监管与政策支持体系。在财务可行性方面，CCUS的发展仍面临挑战，亟需创新的融资模式、碳定价机制以及公私合作伙伴关系的支持。当前全球范围内从试点到商业化的多个CCUS项目，展示了行业不断积聚的推进势能。另外我们还创新碳足迹溯源机制，通过提升透明度、增强市场信心并创造价值，有效推动最终投资决策的落地。

　　This presentation will begin by framing the critical role of CCUS within the GCCA roadmap, emphasizing its contribution to deep decarbonization. It will then explore the key enablers for large-scale deployment, including advances in capture technologies, the need for robust transport and storage infrastructure, and the importance of supportive regulatory frameworks. Financial viability remains a major hurdle, requiring innovative funding models, carbon pricing mechanisms, and public-private partnerships. An overview of the various projects currently in the pipeline —ranging from pilot initiatives to commercial-scale developments—which together signal a growing momentum in the sector will then be provided. Finally, the presentation will highlight how innovative chain-of-custody models—ensuring traceability and verification of captured carbon—could be pivotal in unlocking final investment decisions (FID) by enhancing transparency, market confidence, and value creation across the supply chain.

　　【发言主题】海德堡材料的碳捕获技术：引领绿色未来之路

　　Heidelberg Materials’ Carbon Capture Technology: Leading the Way to a Greener Future

　　【发言摘要】海德堡材料集团正全面推进水泥生产的脱碳战略，重点发展碳捕集、利用与封存（CCUS）技术。作为实现2050年净零排放及2030年近50%减排目标的重要路径，集团已构建起水泥行业内最为先进的CCUS项目组合之一。其技术路线图涵盖多种CCUS技术，包括胺吸收、富氧燃烧、低温冷凝分离、碳酸钾吸收和膜分离系统，现已在全球多个试点及规模化项目中部署。

　　海德堡材料集团的CCUS战略与其他脱碳举措紧密结合，包括提高替代燃料使用比例、扩大补充胶凝材料（SCMs）应用等，以构建协同高效的碳减排路径，确保运营效率和产品质量的同时，大幅降低水泥生产的碳排放强度。

　　Heidelberg Materials is presenting its comprehensive strategy to decarbonize cement production, with a strong emphasis on Carbon Capture, Utilization, and Storage (CCUS) technologies. As part of its commitment to achieving net-zero emissions by 2050, and a nearly 50% reduction by 2030, the company is pioneering one of the most advanced CCUS project portfolios in the sector.

　　The roadmap includes several CCUS technologies such as amine scrubbing, oxyfuel combustion, cryogenic separation, potassium carbonate absorption, and membrane-based systems. These are being deployed across a global network of pilot and full-scale projects.

　　The company’s CCUS strategy is integrated with broader decarbonization levers, including increased use of alternative fuels and supplementary cementitious materials (SCMs). Together, these initiatives form a cohesive approach to reducing the carbon intensity of cement production, while maintaining operational efficiency and product quality.
