Abstract
A thixotropic cement-based paint composition and method wherein the composition is formed by combining Portland cement with presized filter particles having a predetermined relationship by weight to the cement. Water is combined in a volumetric proportion to form an average viscosity of about 3,000 to 8,000 centipoise.
Claims21
A composition for forming a cement base paint having thixotropic flow properties when mixed with water comprising an hydraulic cement in combination with presized particles of inorganic filler with the filler particles having a maximum particle size of about 50 microns and having a minimum relationship by weight to the cement of P/2.ltoreq.F;
- where P represents the cement and F represents the filler particles wherein said hydraulic cement and said presized filler particles are capable of causing thixotropy in the composition when combined in the aforementioned relationship in a mixture with water without the addition of any other ingredient or additive.
A method of forming a cement base paint having substantial thixotropic properties, comprising;
- intermixing portland cement with presized inorganic filler particles having a maximum particle size of about 50 microns in a weight relationship to the portland cement wherein the filler particles by weight equals at least one-half the weight of the portland cement;
- and adding water to form a slurry with a consistency based on an average viscosity of between about 300 to about 8000 cps (centipoises).
