A tool kit approach to re-using historical steel waste

混凝土是世界上仅次于水的第二大使用物质，这主要是因为它的低成本、丰富和在各种环境中的可靠性。虽然混凝土可以追溯到古埃及人、希腊人和罗马人，但目前的生产和利用方法对能源和排放构成了巨大的挑战。我们正在提议钢铁和水泥行业之间的合作，将历史上遗留在泻湖或矿渣堆中的钢铁废料作为大地聚合物水泥材料的来源。与普通波特兰水泥相比，这将使我们从根本上减少高达85%的排放。我们还将能够使工业场地上的土地恢复活力，以创造新的经济，例如Teesworks场地成为自由港。在这个项目中，Teesworks将被用作我们如何建立一个工具包方法来重新利用钢铁遗址及其历史废物的活生生的例子。我们将创造一种循环的方法来处理这种历史废物，并用它来制造新型的大地聚合物水泥。英国的市场机会是巨大的，目前水泥短缺、价格上涨和二氧化碳排放成为建设项目的决定性因素。我们处于一个完美的位置，可以消除我们对向英国进口水泥的依赖，通过重复利用目前被送往垃圾填埋场的废物，实现自给自足地满足我们的水泥需求。

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 the building block of society dating back to the ancient Egyptians, Greeks, and Romans, current production and utilization methods pose significant energy and emissions challenges. We are proposing a collaboration between the steel and cement industry to reuse historical steel waste left on site in lagoons or slag piles as a source of geopolymer cement material.This will allow us to radically reduce emissions up to 85% when compared to Ordinary Portland Cement. We will also be able to rejuvenate land on industrial sites to create new economies, for example the Teesworks site becoming a free port.Within this project, Teesworks will be used as a working example of how we build a toolkit approach to reusing steel sites and their historical waste. We will create a circular approach to this historical waste and use it to make novel geopolymer cements. 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.
