Abstract
A composition comprising at least one binder coated with at least one metallate additive according to formula 1: (RO)m-M-(Oa˜Xb˜R′c˜Yd)n (formula 1), wherein M is one of titanium and zirconium. The composition is particularly useful in producing treated binders and construction materials, wherein the resulting treated binders and construction materials have advantageous properties, such as increased strength. Also disclosed are methods of preparing the inventive composition, treated binders and construction materials.

A method of producing a composition, the method comprising:
- spray coating the surface of at least one binder, wherein the binder is a Portland cement, with an aqueous solution or an aqueous emulsion comprising at least one metallate additive according to formula 1:
- (RO)m-M-(OA—Xb—R′c—Yd)n (formula 1)
- wherein:
- M is one of titanium and zirconium;
- R and R′ are independent a monovalent alkyl, alkenyl, alkynyl, aralkyl, aryl or alkaryl group having up to 20 carbon atoms or a halogen or ether substituted derivatives thereof;
- O is oxygen;
- X is selected from the group consisting of carboxyl, alcoholate, sulfonyl, phosphate, pyrophosphate, and phosphite;

- wherein:
- M is one of titanium and zirconium;
- R and R′ are independently a monovalent alkyl, alkenyl, alkynyl, aralkyl, aryl or alkaryl group having up to 20 carbon atoms or a halogen or ether substituted derivatives thereof;
- O is oxygen;
- X is selected from the group consisting of carboxyl, alcoholate, sulfonyl, phosphate, pyrophosphate, and phosphite;
- Y is one of a methacrylate, acrylate, mercapto and an amine group;
- m is an integer from 1 through 4;
- n is an integer from 0 through 3;
- and
- a, b, c and d are independently either 0 or 1;
- and
- mixing the composition with an additional binder in a mixing device, wherein the reaction temperature of the composition and the additional binder is 168° F.
