ABSTRACT:
A highly stabilized colloidal system is disclosed comprising(a) 30 to 45 volume percent of a liquid phase comprising C15–C20 saturated hydrocarbons, C18–C25 unsaturated hydrocarbons and paraffinic mineral oil; and(b) 55 to 70 volume percent of a solid phase comprising a carbon fraction, a thickener, calcium carbonate and alumina. The highly stabilized colloidal system is used for improving the physical, mechanical, and chemical properties of building materials.
