The incorporation of 40% limestone dust at 0.50 water-to-cement ratios was found to improve the compressive strength of the concrete and resulted in the maximum compressive strength.

ASTM Test Results

Pilgrim Limestone 5.12%; Cottonwood Limestone 3.93%; Corinthian Granite 0.17%; Summit Granite 0.076%; Compressive Strength. Compressive Strength is the stress, in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection.

Pillar Strength and Design Methodology for Stone Mines

Pillar strength can be defined as the maximum resistance of a pillar to axial compression (9). In flat lying deposits, pillar compression is caused by the weight of the overlying rock mass. Empirical evidence suggests that pillar strength is related to both its volume and its shape (4, 6, 9). Numerous equations have been
