【 摘 要 】

It took SS (sewage sludge), PFA (pulverized fuel ash) and BS (building spoil) as raw materials to carry out experiments. An orthogonal experimental design was used to arrange experiments on the mixture ratio and processing parameters to find out a better ratio of green pellets and the right parameters of firing process. In accordance with the right ratio and processing parameters, experiments were carried out by MF (Muffle furnace) to produce lightweight aggregates. The characteristics of products such as 1h water absorption rate, packing density, particle strength were tested. According to the results of orthogonal experiment and range analysis, the optimized parameters suitable for different products requirements were selected. The repeatability of the optimized parameters is proved by the repeated experiments of the same batch, and the corresponding product performance is stable.
