The result shows that, when expansion agent is added, shrinkage can he compensated at some extent and crack can be restrained or reduced effectie1y and then the concrete ageing resistance can he enhanced, and under experiment condition, the appropriate mix content of the expansion agent should be less than 6 %, finally, for compensation shrinkage concrete, the restrictive expansion rete should he the primary index
結果表明，加入膨脹劑能補償部分收縮，有效抑制或減少裂縫的產生，提高混凝土的耐久性；試驗條件下試驗所用膨脹劑的適宜摻量應小於6 % ；對補償收縮混凝土，其限制膨脹率應作為第一性指標。
