摘要
采用砂浆棒快速法对鄂北地区水资源配置工程2016年第2标段七方(罗家)明渠—七方(园林)明渠施工中不同掺量的粉煤灰抑制骨料碱活性效果进行试验。试验选取3组不同骨料,通过掺入不同量的粉煤灰,检测其抑制碱骨料反应效果。结果表明,当粉煤灰掺量为20%时,能有效抑制碱骨料反应,保障混凝土施工质量。
Rapid mortar -bar method had been adopted to test the results of aggregate alkali activity with different mixing amounts during the construction of No.2 bidding section of 2016 - Qifang Open Canal for Luojia and Qifang Open Canal for Yuanlin of Water Resources Allocation Scheme in North Hubei Province. Three types of aggregates were selected for experiment, so as to get the results of controlling aggregate alkali activity through mixing various amounts of coal ashes. The results shows that aggregate alkali activity can be controlled when 20% of coal ashes are added that can ensure quality of concrete construction.
