| 摘 要： | 为了探索生活垃圾焚烧飞灰资源化利用途径,在对飞灰化学组成及矿物成分分析的基础上,利用飞灰、黄陶土、耐火砂及长石研制陶瓷砖,最佳配比方案为:飞灰20%,黄陶土60%,长石10%,耐火砂10%,分析了最佳配比制品的吸水率、抗压强度、微观结构及水平振荡浸出毒性。结果表明:飞灰属SiO2-Al2O3-金属氧化物体系,主要矿物成分是钙硅酸盐及铝硅酸盐等,可用于制陶瓷砖;最佳配比制品达MU15强度等级,满足抗风化的要求;随煅烧温度的升高,制品结构不断密实化,960℃烧成的制品显示出完全烧结的特点,960~1 000℃烧成的制品中出现明显的晶化、玻璃化过程。最佳配比制品重金属浸出毒性完全达标,重金属的浸出率与坯体相比大大降低。 |

| Abstract: | Based on chemical and mineralogical composition analysis,MSWI fly ash,together with yellow ceramic clay,ripe sand and feldspar,was used to make ceramic brick,to explore a new way of fly ash recycling.An orthogonal test was designed to determine the optimum mixing ratio of materials,which registers 20% fly ash,60% yellow ceramic clay,10% feldspar and 10% ripe sand.Besides,water absorption,compressive strength,microstructure and HVEP leaching toxicity were performed on ceramic bricks made in accordance with t... |
