目前我国粉煤灰砖的生产还离不开骨料,这是因为粉煤灰的特性和现有成型设备的功能所限的原因。传统的经验指出:粉煤灰砖的生产应掺入一定量的粗颗粒含硅材料(如炉渣、高炉水淬矿渣、硬矿渣及砂子等),使混合料具有适宜的颗粒级配,以改善砖坯的成型性能。为此,有的工厂则四处搜集煤渣,有的工厂使用水淬矿渣与水 At present, the production of fly ash bricks in China is still inseparable from the aggregates, which is due to the characteristics of fly ash and the limitations of the existing molding equipment. Traditional experience points out that: The production of fly ash bricks should incorporate a certain amount of coarse-grained silicon-containing materials (such as slag, blast furnace water quenched slag, hard slag, and sand, etc.), so that the mixture has a suitable particle size distribution to improve Brick forming performance. For this reason, some factories collect cinders everywhere, and some plants use water-quenched slag and water.
