Deterioration of light-weight aggregate concrete due to frost damage is heretofore considered to be caused by deterioration of a part of cement pastes. But it is very difficult to explain the resistance to freezing and thawing of high-strength light-weight aggregate concrete consist of fine cement pastes and light-weight coarse aggregates with these water content of several percent mainly depends on only a part of cement pastes. This paper describes deterioration of high-strength light-weight aggregate concrete due to frost damage depends on not deterioration of cement pastes but that of light-weight aggregates.
