摘要
Abstract
Due to the high strength grade of concrete in bridge engineering,the content of fly ash is generally lower than 30％.In order to explore the inhibition effect of low content fly ash on alkali activity,three fly ash contents of 14％,20％and 25％are selected according to the actual situation of a project to carry out the effectiveness test of inhibiting alkali activity.When different testing methods were used to verify the effectiveness of fly ash in inhibiting alkali activity,the results were inconsistent.When the mortar rod rapid method was used,the inhibition effect of Class F Class I fly ash with 14％,20％and 25％content on the alkali aggregate reaction hazard was assessed as effective.关键词
