What is Freeze-Thaw Damage in Concrete about?

This document discusses freeze-thaw damage in concrete caused by water freezing within pores. It explains that water expands by about 9% when it freezes. Repeated freezing and thawing within confined pores puts stress on concrete and can lead to cracking over time. Damage types include surface scaling, D-cracking of aggregates, and aggregate pop-outs. Scaling removes surface material while D-cracking and pop-outs are caused by aggregate damage. Susceptibility depends on factors like aggregate pore structure
