Experimental study on freeze-thaw damage mechanism of lightweight aggregate concrete.

Author(s) : MAO J., AYUTA K., QI H., et al.

Type of excerpt: Book chapter

Summary

In this study (reprinted from the Journal of ASTM International), rapid freezing and thawing tests were conducted on lightweight concrete and lightweight coarse aggregate, respectively. The results of the concrete tests showed that the freeze-thaw resistance of lightweight concrete was mainly controlled by the water content of the lightweight aggregate. The tests of lightweight aggregate produced similar results: the higher the water content of the aggregate, the higher the weight loss and grain ratio passing 10 mm sieve; the lower the crushing strength, the larger the pore volume after freezing and thawing.
