A study of components of the binding (matrix) system of new refractory concretes. Part I. components and general characteristics of binding systems

New refractory concretes (such as ceramic castables and super-low-cement concretes) are considered and analyzed as composite materials consisting of a highly disperse binding system (matrix) and a polydisperse refractory filler. The mineral and grain compositions of binding systems used in fabricating ceramic castables and low-cement concretes are characterized. HCBS are characterized by the presence of ultradisperse particles in their composition (a colloidal component < 0.1 (μm) which determine the binding properties. A pioneering definition of a binding system for new refractory concretes is suggested.
