Abstract
A process of producing a colloidal mortar suitable for use as a lining of steel conduit pipes, boilers or the like, includes filling a mixer with water while imparting to water a rotary motion by a rotary agitator at a speed of 1500 m/minutes, feeding the mixer with cement while maintaining the rotary motion whereby the mixture forms a funnel-like profile within the mixer and adding to the mixture wet sand of humidity of 5-15% and in proportion of 1 to 2 parts of the cement content to obtain the colloidal mortar. Fiber rovings may be added to the colloidal mortar.
