Abstract: The study examines the durability of Minnekahta limestone and Sioux quartzite used for concrete aggregates in South Dakota due to freezing and thawing. Vacuum saturated and dry specimens of these rocks are subjected to 100 cycles of freezing and thawing with a temperature range of 0 to 40°F. (-l8 to 4.4°C.) The saturated specimens show an increase in absorption, decrease in tensile strength and decrease in modulus of elasticity after 100 cycles of freezing and thawing. No consistent variation in Poisson's ratio and compressive strength are observed due to 100 cycles of freezing and thawing. Reasonable agreement between the increased absorption and the increased permanent volume change based on the measured change in length due to freezing and thawing is obtained. A relative durability rating for these rocks indicates that both these rocks are good for concrete aggregates. Smaller size quartzite and larger size limestone are better from the standpoint of resistance of concrete to freezing and thawing.
