［摘要］延遲性鈣礬石反應多發(fā)生在大體積混凝土中或蒸壓養(yǎng)護的預制混凝土構件中，發(fā)生在一般的民用住宅建筑中非常罕見，因此往往引起誤判。通過近年來遇到的一些工程案例，對工程事故的概況進行介紹，描述了工程事故的分析、檢測、加固、復檢及分析的過程，對發(fā)生延遲性鈣礬石反應的成因進行分析，并提出了對這種工程事故處理的方法。由于這種工程事故非常罕見，處理效果尚待長期的時間檢驗。
［關鍵詞］延遲性鈣礬石反應； 異常粗骨料； 原因分析； 加固方法

Abstract:Most of the delayed ettringite reactions occur at the mass concrete or the precast concrete components of autoclaved curing, and are rarely seen at the general civilian residential buildings, so misjudgment is often caused. Through some engineering cases encountered in recent years, the general situation of engineering accidents was introduced, and the process of analysis, detection, reinforcement, reinspection and analysis of engineering accidents was described. The causes of the delayed ettringite reaction were analyzed, and the methods for this engineering accident were put forward. Because this kind of engineering accident is very rare, the treatment effect needs to be inspected for a long time.
Keywords:delayed ettringite reaction; abnormal coarse aggregate; reason analysis; reinforcement measures
