Descriptions
Freezing and thawing test of water saturated samples of crushed stone was performed, and weight loss was determined screening the samples after the freezing and thawing test by diminution of grain size. It was recognized that there were correlationships between the weight loss by the freezing and thawing and soundness, specific gravity or absorption. Consequently it could be reasoned that the soundness test of crushed stone is an effective measure for estimation of resistance to freezing and thawing. Effects of grain size on the weight loss, elongation and variation of ultrasonic wave velocity of rock specimens due to repetition of freezing and thawing were also examined.
