| 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。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。

| Abstract: | Applying low-quality fly ash to concrete is an efficient approach to reduce the pollution of waste matter. 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. |
