摘要
对电厂生物质燃料余灰在压制成型水泥基材料(瓦)中的应用进行研究,并在水泥瓦实际生产线上进行了试生产,结果表明:在灰砂比2∶3、水灰比为0.26的条件下,随着余灰掺量的增加,水泥试块的抗折强度呈明显下降趋势,而吸水率却逐渐增大;余灰取代30%水泥、憎水剂硬脂酸钙掺量为1.0%,水泥试块抗折强度、吸水率及抗冻性指标综合最优。在掺有憎水剂硬脂酸钙的情况下,余灰取代部分水泥(30%)生产水泥瓦是可行的。
The application of the wastes produced by biomass power plants on the making of cement-based materials production is studied with pilot production. The result shows that rupture strength of the cement specimens is decreased obviously and their water absorption increase gradually with rising amount of the wastes when cement sand ratio is 2/3 and water cement ratio is 0.26. Rupture strength, water absorption, frost resistance of cement specimens are good when the wastes replace 30% cement and the content of water repellent is 1.0%. It＇s feasible to produce cement tiles under the conditions aforementioned.
