Claim 6
Independent Claim
122 words
The method which comprises intergrinding a solid, inorganic compound selected from the group consisting of naturally occuring mineral compounds, Portland cement clinker, magnesia and beryllium oxide, an amount of an additive consisting of a salt of an amine selected from the group consisting of morpholine and an alkandamine wherein the alkanol group contains about one to five carbon atoms and an aryl hydroxy compound wherein the aryl radical is selected from the group consisting of phenyl, naphthyl and substituted phenyl and naphthyl wherein the substituent is selected from the group consisting of nitro, halo, alkyl of 1-5 carbon atoms, aryl, amino and alkoxy of 1-5 carbon atoms, the amount of said additive being sufficient to enhance the efficiency of the grinding operation.
Claim 7
Dependent Claim
24 words
The method of claim 7 wherein said amount is about 0.001 to 1 percent by weight, based on the weight of the solid compound.
Claim 8
Dependent Claim
19 words
The method of claim 7 wherein the solid inorganic compound is Portland cement and said additive is triethanolammonium phenoxide.
Claim 9
Dependent Claim
93 words
A composition consisting essentially of Portland cement, and, intimately admixed therewith, about 0.001 to 1 percent by weight, based on the weight of said Portland cement, of an additive consisting of a salt of an amine selected from the group consisting of morpholine and triethanolamine and an aryl hydroxy compound wherein the aryl radical is selected from the group consisting of phenyl, naphthyl and substituted phenyl and naphthyl wherein the substItuent is selected from the group consisting of nitro, halo, alkyl of 1-5 carbon atoms, aryl, amino and alkoxy of 1-5 carbon atoms.
Claim 10
Dependent Claim
24 words
The composition as defined in claim 10 wherein said amine comprises a mixture of morpholine and triethanolamine and said aryl hydroxy compound is phenol.

Claim 12
Dependent Claim
29 words
The composition as defined in claim 10 wherein the amount of additive employed is about 0.004 to 0.04 percent by weight, based on the weight of said Portland cement.
Claim 13
Independent Claim
90 words
The method which comprises intergrinding Portland cement with about 0.001 to 1 percent by weight, based on the weight of said Portland cement, of an additive consisting of a salt of an amine selected from the group consisting of morpholine and triethanolamine and an aryl hydroxy compound wherein the aryl radical is selected from the group consisting of phenyl, naphthyl and substituted phenyl and naphthyl wherein the substituent is selected from the group consisting of nitro, halo, alkyl of 1-5 carbon atoms, aryl, amino and alkoxy of 1-5 carbon atoms.
Claim 14
Dependent Claim
13 words
The method as defined in claim 14 wherein said additive is triethanolammonium phenoxide.
Claim 15
Dependent Claim
28 words
The method as defined in claim 14 wherein the amount of the additive is about 0.004 to 0.04% by weight, based on the weight of said Portland cement.
