The experiment results show that that the elastic modulus is reduced when fly ash only was added to RAC and present a significant difference with the rate of fly ash and slag content.
In column experiment during 21 days, it was observed that the granulated fly ash could continuously remove the phosphorus under high hydraulic loading rate.
还进行了为期21天的连续过滤试验，发现滤床在高水力负荷条件下能持续地去除景观水中的磷。

The slagging, fouling and abrasiveness performances of co-firing low-temperature pyrolyzed biomass with coal depend on the ash content, the ash component of them and their blending rate, etc.
