摘　　要：介绍了一种粉煤灰掺量可达60％～87％的制砖新技术。试验选取电厂排出的细湿粉煤灰．加入配比合理的骨料和添加剂制造高掺量粉煤灰砖，试验结果表明，制作的高掺量粉煤灰建筑砌砖的强度等级和抗冻融性等指标均可达到国家建材行业标准。The paper gives an introduction of a new technology of making construction brick from high percentage (60%-80%) of fine coal dust. In the test, the high fine coal dust brick is made from selected fine wet coal dust from power plant, which is mixed with reasonable percentage of bone material and additive. It is shown from test the brick made with this technology can meet the national standard with respect to intensity and freezing resistance property etc.
