<p>A capsule contains in separate compartments the interactive components of a self-setting composition which comprise as base component a paste of high alumina cement, retarders, water, and a source of CaO and SiO2 - e.g. preferably granulated blast furnace slag or alternatively fly ash, silica fume, a pozzolan or diatomaceous earth; and as a catalyst component a paste of lime, water and a water-soluble lithium salt. When reacted the components form a set cement containing hydrated phases typical of an OPC.</p> |
