Effect of Curing Condition in Early Age on Variation of Pore Structure and Carbonation of Fatigued Mortar

초기양생조건이 피로를 받은 모르터의 세공구조와 중성화의 변화에 미치는 영향

This paper was studied to effects of fatigue by low flexural load on micro structures and carbonation of mortar. Mortar specimens cured at various conditions were first subjected to bending repeated loads, and it was made clear that insufficient cure reduced fatigue resistance of them. Next, fatigue tests that the stress levels are lower than the ones of fatigue rupture were carried out, The effect of curing conditions in early age on carbonation was furthermore studied using the scale, and it was made clear that insufficient cure is also susceptible to carbonation of them. Finally, the reason for rapid carbonation of fatigued mortars insufficiently outed was discussed from the view point of changes in pore structure of them.
