Applications:

Coarse aggregate in portland cement concrete

Coarse aggregate in portland cement concrete pavements

Pipe bedding material

Description:

A coarse aggregate, produced by crushing, washing and screening high calcium or dolomitic limestone. A white to light gray colored sedimentary rock formed by the precipitation of calcium carbonate from seawater. The particles are sized from 1½” (37.5mm) to ⅜” (9.5mm).

Specs:

Michigan Department of Transportation

6AA Limestone conforms to all the requirements of Michigan Department of Transportation (M•DOT) “2012 Standard Specifications for Construction”, section 902

Usage Guide:

The 6AA Limestone should be blended into the concrete mixture along with the cement, fine aggregate, water, admixtures and any special additives in the proportions detailed in the mix design. Care needs to be taken to minimize the amount of handling of the 6AA Limestone as handling operations will cause ‘dusting’ of the aggregates particles, increasing the amount of material passing the #200 mesh (75µm sieve).
