摘要/Abstract

摘要： 提出一种新的骨料碱活性检测方法———溶胶－凝胶膨胀法并用其对蛋白石和天然骨料的碱活性进行了研究．试验结果表明利用溶胶－凝胶膨胀法蛋白石表现出明显的碱活性并且发现在蛋白石掺量为最劣点时的溶液中 SiO2含量和 SiO2／Na2O 摩尔比都达到最值膨胀量也达到最值．

关键词: So-l gel 膨胀法, 蛋白石, 碱骨料反应, 骨料活性

Abstract: The application of a new test method for aggregate alkali activityso-l gel expansion method was presentedwhich was used to investigate the alkali activities of opal and natural aggregate．The experimental results show that by using the methodopal shows significant alkali activityand at the pessimum proportion of opalboth SiO2 content and SiO2／Na2O mole ratio in the reaction solution reach their maximum valuesand so is the expansion．

Key words: so-l gel expansion method, opal, alkal-i aggregate reaction, aggregate activity
