摘要
大量低品质粉煤灰在混凝土中的应用,是减轻燃煤废料污染、缓解矿物能源危机的有效途径。本文试验用较低品质粉煤灰配制中高强度混凝土,比较了粉煤灰品质、掺量,水胶比和胶凝材料总量对混凝土抗压强度的影响,认为水胶比和粉煤灰掺量对混凝土强度起主要作用,在低水胶比前提下,粉煤灰品质的影响不大。
The application of low-quality fly ash to concrete is a efficient approach to reduce the pollution of waste metter.Based on the tests,the factors which affect the compressive strength oF low-quality fly ash concrete are investigated.The analysis result shows that the influence of water-binder ratio on the strength of low-quality fly ash concrete is the greatest,then the fly ash content,and then the binder composition.At the same time,the effects of fly ash quality on the strength of concrete are presented.
