1) alkali reacted aggregate
碱活性骨料
2) aggregate activity
骨料活性
4) alkali-reactivity of aggregate
集料碱活性
1.
Since the first accident of Alkali-Aggregate Reaction(AAR) found,with the increasing magnitude usage of aggregate inconcrete structure,the engineer realize that alkali-reactivity of aggregate is the most important influencing factor on durability ofaggregation,so the evaluating methods for potential alkali-reactivity of aggregate is the key parameter for controlling concrete quantity.
最后对集料碱活性分析步骤进行讨论,使得碱活性测试更为合理、有效。
5) Alkali-reactive Aggregate
碱活性集料
6) non active aggregate
非活性骨料
1.
It has been proved through study results that artificial granite aggregate is non active aggregate judged by present criterions.
研究结果表明 ,用现有标准判断 ,花岗岩为非活性骨料。
补充资料：碱骨料反应
当骨料中含有活性氧化硅颗粒时,会与水泥中的碱类发生反应,使混凝土发生不均匀膨胀,造成裂缝,强度和弹性模量下降等不良现象,从而威胁工程安全.这种现象称为碱骨料反应.
