  • Activator composition and method for making concrete
    Patent number: 10696590
    Abstract: An activator composition for a non-OPC hydraulically-active material comprises CaO or lime and a polycarboxylate-ether-based (PCE) superplasticiser, and is mixable with a hydraulically active material comprising ground granulated blast furnace slag (GGBS) and/or pulverized fuel ash (PFA) to form a cementitious binder. The cementitious binder does not comprise any Portland cement and is, therefore, more environmentally friendly.
    Type: Grant
    Filed: October 25, 2017
    Date of Patent: June 30, 2020
    Assignee: DB GROUP (HOLDINGS) LTD
    Inventors: David Martin James Ball, Martin Liska, Peter Hewlett
  • Cementitious binders, activators and methods for making concrete
    Patent number: 10399897
    Abstract: A cementitious binder comprises at least 90% by weight of a hydraulically-active material comprising ground granulated blast furnace slag (GGBS) and/or pulverised fuel ash (PFA), and at least 0.1% by weight of CaO in an activator composition for the hydraulically-active material. The cementitious binder does not comprise any Portland cement and is, therefore, more environmentally friendly. The binder further comprises a superplasticiser such as a polycarboxylate ether (PCE). A concrete, mortar, grout, screed or render may be formed from a mixture of the cementitious binder, aggregate particles, water and superplasticiser.
