The batch composition may be mixed with sufficient water to cause the cementious material in the batch composition to set and bind the entire mass to form a concrete. ## Claims ### Claim 1 A method for forming concrete, comprising: providing a batch composition for concrete comprising a cementious material and aggregate material, the cementious material including at least 50% by weight Portland cement and at least 1% by weight dolomite mineral filler; feeding the aggregate material, Portland cement, and dolomite mineral filler separately into a mixer; and mixing the batch composition with sufficient water to cause the cementious material in the batch composition to set and bind the entire mass to form a concrete; wherein the dolomite mineral filler is a granular powder having a sizing of 99% or more passing a 20 mesh sieve, 5% to 75% passing a 50 mesh sieve, 35% to 65% passing a 100 mesh sieve, 5% to 35% passing a 200 mesh sieve, and no more than 15% passing the 325 mesh sieve. ### Claim 2 (depends on 1) The method of claim 1, wherein the cementious material includes at least 10% by weight dolomite mineral filler. ### Claim 3 (depends on 1) The method of claim 1, wherein the dolomite mineral filler has a moisture content of 0.2 weight % or less. ### Claim 4 (depends on 1) The method of claim 1, wherein the batch composition is mixed with water to form a mixture in which the water is 5 to 6%, by weight. ### Claim 5 A method for forming concrete, comprising: providing a batch composition for concrete comprising a cementious material and aggregate material, the cementious material including at least 50% by weight Portland cement and at least 1% by weight dolomite mineral filler; feeding the aggregate material, Portland cement, and dolomite mineral filler separately into a mixer; and mixing the batch composition with sufficient water to cause the cementious material in the batch composition to set and bind the entire mass to form a concrete; wherein the dolomite mineral filler is a powder having a sizing of 90% or more passing a 100 mesh sieve, 50% or more passing a 200 mesh sieve, and no more than 40% passing a 325 mesh sieve. ### Claim 6 (depends on 5) The method of claim 5, wherein the cementious material includes at least 10% by weight dolomite mineral filler. ### Claim 7 (depends on 5) The method of claim 5, wherein the dolomite mineral filler has a moisture content of 0.2 weight % or less. ### Claim 8 (depends on 5) The method of claim 5, wherein the batch composition is mixed with water to form a mixture in which the water is 5 to 6%, by weight. ### Claim 9 A method for forming concrete, comprising: providing a batch composition for concrete comprising a cementious material and aggregate material, the cementious material including at least 50% by weight Portland cement and at least 1% by weight dolomite mineral filler; feeding the aggregate material, Portland cement, and dolomite mineral filler separately into a mixer; and mixing the batch composition with sufficient water to cause the cementious material in the batch composition to set and bind the entire mass to form a concrete; wherein the dolomite mineral filler is a powder having a sizing of 97% or more passing a 100 mesh sieve, 80% or more passing a 200 mesh sieve, and no more than 65% passing a 325 mesh sieve. ### Claim 10 (depends on 9) The method of claim 9, wherein the cementious material includes at least 10% by weight dolomite mineral filler. ### Claim 11 (depends on 9) The method of claim 9, wherein the dolomite mineral filler has a moisture content of 0.2 weight % or less. ### Claim 12 (depends on 9) The method of claim 9, wherein the batch composition is mixed with water to form a mixture in which the water is 5 to 6%, by weight. ### Claim 13 A method for forming concrete, comprising: providing a batch composition for concrete comprising a cementious material and aggregate material, the cementious material including at least 50% by weight Portland cement and at least 1% by weight dolomite mineral filler; feeding the aggregate material, Portland cement, and dolomite mineral filler separately into a mixer; and mixing the batch composition with sufficient water to cause the cementious material in the batch composition to set and bind the entire mass to form a concrete; wherein the dolomite mineral filler is a very fine powder having a sizing of 90% or more passing a 325 mesh sieve. ### Claim 14 (depends on 13) The method of claim 13, wherein the cementious material includes at least 10% by weight dolomite mineral filler. ### Claim 15 (depends on 13) The method of claim 13, wherein the dolomite mineral filler has a moisture content of 0.2 weight % or less. ### Claim 16 (depends on 13) The method of claim 13, wherein the batch composition is mixed with water to form a mixture in which the water is 5 to 6%, by weight.
