Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
48 words
A system for producing a pigmented cement composition consisting essentially of: (a) a powder cement component; and (b) an aqueous pigment component wherein the cement component and pigment component are separately packaged and mixed together prior to use to produce a composition with a uniform and standardized color.
Claim 2
Independent Claim
48 words
A system for producing a pigmented cement composition consisting essentially of: (a) a powder cement component; and (b) an aqueous pigment component wherein the cement component and pigment component are separately packaged and mixed together prior to use to produce a composition with a uniform and standardized color.
Claim 3
Dependent Claim
16 words
A system as defined in claim 1 wherein the cement component comprises cement and inert fillers.
Claim 4
Dependent Claim
30 words
A system as defined in claim 2 wherein the cement is selected from the group consisting of portland cement, portland blast-furnace slag cement, portland-pozzolan cement, aluminous cement and mixtures thereof.
