RESCIND will harness the value in two continuously produced waste streams: Pulverised Fuel Ash (PFA, ‘fly ash’) from coal-fired power stations and Cement Kiln Dust (CKD) from the production of cement to develop a low-carbon building product. CKD is a by-product of cement clinker production which generates significant disposal costs for the cement industry. CKD can be used with PFA, or other silicon rich material, to produce a cement replacement. . This “cementless” binder can wholly replace Portland cement in concrete production and in conjunction with recycled aggregate enables “all waste” concrete products. RESCIND will demonstrate the use of CKD as an enabling material for cementless concrete block production. Cementless concrete blocks will be manufactured and mechanically tested to demonstrate performance. Through the use of recycled demolition aggregate, “all-waste” concrete will be demonstrated

RESCIND 将利用两种持续产生的废物流的价值：来自燃煤发电站的粉煤灰（PFA，“飞灰”）和来自水泥生产的水泥窑粉尘（CKD），以开发低碳建筑产品。 CKD 是水泥熟料生产的副产品，会给水泥行业带来巨大的处置成本。 CKD 可以与 PFA 或其他富含硅的材料一起使用，以生产这种“无水泥”粘合剂。可以在混凝土生产中完全取代波特兰水泥，并与再生骨料结合使用，使“全废物”混凝土产品能够使用 CKD 作为无水泥混凝土砌块生产的有利材料，并将进行无水泥混凝土砌块的生产和机械测试。通过使用再生拆除骨料，将展示“全废弃”混凝土。
