摘要
经过大量试验,初步探讨了粉煤灰掺量、胶水比、养护温度对混凝土28天强度的影响规律,建立的三元数学模型较好地描述了这一强度增长规律。对于粉煤灰混凝土的试配和现场施工,这一数学模型有积极的指导作用。
According to the amount of tests, the effect law of mixing ratio of fly ash, cement water ratio, curing temperature to concrete strength of 28 days is discussed, the test mixing and the strength improving law is expressed through three dimensions mathematics model. And the mathematics model directs the test mixing and site operation of fly ash concrete.
