摘要
对10个省区百余座输水建筑物运行情况进行调查结果表明:碱集料破坏反应已成为当前水泥混凝土输水建筑物的主要病害之一;;非严寒地区输水建筑物水泥混凝土施工中掺加适量粉煤灰可有效地抑制碱集料破坏反应。
The investigation on service condition ofalmost one hundred water iran sport construCtionsover ten provinces shows that AAR has alwaySbeen one major hazard on cement concrete andwater transport construCtions. On unfreeZing areas,adding suitsble fly ashes tO cement concretsof water transport construCtions can aCtively avoidor inhibite AAR.
