Abstract
A batch composition for concrete includes a cementious material and aggregate material, the cementious material including at least 50% Portland cement and at least 1% of a dolomite mineral filler. 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.
Claims16
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.
