Concrete is the second most used substance in the world after water, largely due to its low cost, abundance, and reliability in a wide variety of environments. While concrete has been a building block of society dating back to the ancient Egyptians, Greeks, and Romans, current production and utilization methods pose significant energy and emissions challenges.This research proposes a resource and energy efficiency opportunity in the cement industry, which is the main carbon emitter within concrete, by utilising industrial by-products from the steel industry to create a new cement and establish a circular economy between these two foundation industries. We need to rapidly and radically decarbonise the foundation industries in the UK, and we can do this by improving resource efficiency.The main motivation for this project is to take our existing technology developed by Material Evolution (utilising 95% waste and saving 85% CO2 emissions) to market quicker in the use case of soil stabilisation, whilst creating new skilled jobs in geotechnical fields and using waste material local to Teesside to remediate land on the freeport.The market opportunity is huge in the UK with current cement shortages, rising prices and CO2 emissions becoming a deciding factor in the construction projects. We are in a perfect position to remove our reliance on importing cement into the UK, becoming self-sufficient in our cement needs by reusing waste currently sent to landfill.

混凝土是世界上仅次于水的第二大使用物质，主要是由于其成本低，丰富，在各种环境中的可靠性。虽然混凝土一直是社会的基石，可以追溯到古埃及人，希腊人和罗马人，目前的生产和利用方法带来了重大的能源和排放挑战。这项研究提出了水泥行业的资源和能源效率的机会，这是混凝土中的主要碳排放，通过利用钢铁工业的工业副产品来创造新的水泥，并在这两个基础产业之间建立循环经济。我们需要快速、彻底地对英国的基础产业进行脱碳，我们可以通过提高资源效率来做到这一点，这个项目的主要动机是将我们现有的由Material Evolution开发的技术（利用95%的废物，减少85%的二氧化碳排放量）在土壤稳定应用中更快地推向市场，同时在岩土工程领域创造新的技术工作岗位，并利用蒂赛德当地的废料修复自由港的土地。由于目前水泥短缺，英国的市场机会巨大，价格上涨和二氧化碳排放量成为建筑项目的决定性因素。我们处于一个完美的位置，以消除我们对进口水泥到英国的依赖，成为自给自足，在我们的水泥需求，通过再利用废物目前送往垃圾填埋场。
