摘　　要：作者曾在 2 0 0 0年第 4期《砖瓦》杂志上发表了《高掺量粉煤灰烧结砖工艺技术难点探讨》 ,在此基础上再次就生产高掺量粉煤灰烧结砖原料的物理化学性能 ,特别是可塑性、临界含水率、干燥线收缩方面进行了阐述 ,并就原料陈化 ,产品定位等方面进行了有益的探讨 ,对研究开发高掺量粉煤灰砖有一定的参考价值。On the basis of the paper of Discussion on Process Technology Difficult Point for Fired Brick with High Fly ash Additives published in Brick and Tile magazine of No.4, 2002, the paper again discusses on physical properties of fired brick with high fly ash additives, especially on plasticity, critical water content, drying shrinkage. And gives out ideas on materials aging and product name. The paper has an important reference value for developing brick with high fly ash additive.
