Crushed limestone has several important advantages over river gravel as an aggregate for concrete. First, for a given amount of cement in the mix, crushed limestone concrete will have an approximately 10% strength advantage. This strength advantage comes from the fact that cement bonds tighter to limestone than to a slick/smooth gravel and the

Crushed limestone fine sand is a by-product of the quarry process and typically does not have a significant demand due to its high fines content that exceeds the standard allowable limit of 5%. The fines are particles whose diameters are less than 80 μm. For the compressive strength determination cubes of 100 mm in size were used and

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. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.

Crushed Edward’s Limestone Base was inexpensive, easily placed, and resulted in long lasting, smooth riding roads. The only equipment required to place crushed stone base is a motor grader, water truck and compaction roller. By the mid 1950’s, this crushed base material was the standard road building base material in the Austin area.
