CCPDM-Circular cementitious products embedding digital manufacturing

这个由IDoBE中心领导的新项目利用建筑和拆除（C&D）废物和塑料废物，用于增材制造驱动的模块化块原型。它建立了英国和印度两个研究中心之间的虚拟连接。建筑材料促进理事会估计，印度每年产生1.5亿吨建筑和拆除（C&D）废物。然而，只有1.3%的建筑和拆卸废物被回收。印度全国的C&D回收流程缺乏统一性，良好的商业案例有限。在印度的国家清洁空气计划和城市地方机构之后，C&D废物处理也是控制空气质量的关键部分。在英国，C&D废物占年度废物的60%。虽然超过90%的建筑和拆卸废物已被回收，但仍有很大的潜力提高回收的循环价值，例如从废弃物到再利用的建筑产品。该项目旨在将最先进的循环研究和利用拆建废料和塑料废料的开发结合起来，以实现制造模块化砌块的最佳组合设计。它涉及来自C&D和塑料废物的过程和产品。IDoBE中心将领导可行性研究，以确定C&D废物的来源，废物的处理和产品案例。目前在英国的基础行业的挑战，特别是，在拆除现场的砖和混凝土材料的分类，因为他们的组合有负面影响的湿加工厂和性能的沙子和骨料从工厂生产。在印度，SV-NIT实验室正在为目前参与地铁铁路大型项目的承包商提供咨询服务，该项目使用可回收和可重复使用的C&D废料进行建筑。该项目建立在英国团队在将废塑料再利用为3D打印产品方面的现有专业知识基础上，这些产品具有适应性和可重复使用性，可用于成型块。它将通过进一步整合建筑和发展以及塑料废物来扩展IDoBE中心先前的工作，以开发测试块作为商业案例。IDoBE中心的研究团队通过虚拟网络开发英国和印度之间在建筑和土木工程领域利用当地可用材料的知识。该项目计划开展研究传播活动，将当前的研究活动与新兴的增材制造联系起来，以推动在建筑中使用不可持续产品的思维转变。

This new project led by the IDoBE Centre utilises construction and demolition (C&D) wastes and plastic wastes, for an additive manufacturing-driven prototype of modular blocks. It builds the virtual connection between two research centres in the UK and India. Building Material Promotion Council estimated that India generates 150 million tonnes of construction and demolition (C&D) waste annually. However, just 1.3% of the total C&D wastes are recycled. There are a lack of uniformity and limited good business cases in C&D recycling processes in India nationwide. C&D waste handling also forms a key part in controlling the air quality following India's National Clean Air Programme and Urban Local Bodies. In the UK, C&D wastes account for up to 60% of annual wastes. Although over 90% of C&D wastes have been recovered, there is a large potential to improve the circularity value of recovery, such as from backfilling to repurposed building products. This project aims to bridge the state-of-the-art circularity research and development in utilising C&D and plastics wastes to achieve the optimal mix design in manufacturing modular blocks. It addresses the process and products from C&D and plastic wastes. IDoBE Centre will lead the feasibility study to establish the sources of C&D wastes, the processing of wastes, and the product case. Current challenges in the UK foundation industry are addressed, specifically, sorting of brickbats and concrete materials at demolition sites as their mix has a negative impact on wet processing plants and properties of sand and aggregate produced from the plants. In India, SV-NIT Lab is providing consultancy services to contractors currently involved in a Metro rail large project that use recyclable and reusable C&D waste materials for construction.The project builds upon the existing expertise of the UK team in reusing waste plastics for 3D printing products, which are adaptable and reusable for shaping blocks. It will extend the prior work of the IDoBE Centre by further integrating C&D and plastic wastes in developing the testing blocks as the business case. The research team from IDoBE Centre through virtual network develop the knowledge between UK and India in utilising locally available materials in construction and civil engineering sectors. Research dissemination activities are planned in this project to link current research activities into emerging additive manufacturing to drive the change in thinking of using unsustainable products in construction.
