摘要
用外掺轻烧氧化镁微膨胀混凝土的延期膨胀性能来补偿混凝土的温度应力 ,防止基础混凝土裂缝 ,简化温控措施 ,减少浇筑块的分缝 ,是一项加快水利水电建设的有效措施。
The delayed expansion property of adscititious MgO micro expansive concrete compensats temperature stress of concrete,resists foundation concrete cracking,reduces temerature control measure and concrete depositejoint.It is an effective measure to quicken water resouces and hydropower construction project.This article introduces the test's methods and results. 〔
