近年来,粉煤灰作为水泥和混凝土的一个组分,其应用日益广泛。由于经济和工艺方面的优点,这一趋势将在今后若干年继续保持。但是,充分了解其性能,是将其合理应用于水泥和混凝土的必要前提。为了开发粉煤灰的用途,已有各种方法用于测定其特性,包括有关的化学的物理性能,如化学组成,烧失量,细度以及它与石灰或波特兰水泥拌合成砂浆的实际强度检验。事实上,这些测定所提供的依据,对于实际应用的粉煤灰的质量评定未必十分
In recent years, as a component of cement and concrete, fly ash has become increasingly widely used. Due to economic and technological advantages, this trend will continue to be maintained in the coming years. However, full understanding of its performance is a necessary prerequisite for its rational application to cement and concrete. In order to develop the use of fly ash, various methods have been used to determine its properties, including related chemical physical properties such as chemical composition, loss on ignition, fineness, and its mixing with lime or Portland cement. Actual strength test. In fact, the basis provided by these measurements is not necessarily very accurate for the actual application of fly ash quality assessment.
