摘要
水胶比与粉煤灰掺量是决定碾压混凝土强度等性能的重要参数,以往通常采取不断试配调整水胶比与粉煤灰掺量这两个参数来获得合理配合比,但此方法适应性差且较为繁琐。以广东惠州抽水蓄能电站大坝碾压混凝土配合比设计为例,在试验基础上,用数理分析法探究水胶比及粉煤灰掺量对碾压混凝土强度发展的影响规律,并据此得到合理的配合比。该方法设计过程有章可循,且对外界条件变化有较强适应性。其设计方法可供类似工程设计建造工作参考。
Water - cement ratio and fly - ash mixing amount are important parameters for strength and other properties of RCC and proper mixing proportion of RCC is usually obtained by repeatedly adjusting the two parameters that are evidently complex. Taking the dam of Huizhou Pumped Storage Power Station in Guangdong Province as an example, on the basis of text study, we explore the influencing law of water - cement ratio and fly - ash mixing amount on the strength of RCC, and the rational mixing proportion of RCC of the station is calculated utilizing the law. The presented method has rules to follow and possesses a high a- daptability to external conditions.
