Capsules of high alumina cement compositions.

摘要

A capsule containing in separate compartments the interactive components of a self-setting composition which comprises as the basic component a paste having a high alumina cement, water and a source of CaO and SiO2, e.g. as a single-source granulated blast furnace slag, 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 for an Ordinary Portland cement.
