More Information
Summary:The invention discloses a foamed ceramic prepared from steel slag and a preparation method thereof, and belongs to the technical field of building materials. The foamed ceramic comprises the followingraw materials in parts by weight: 100-150 parts of steel slag, 25-30 parts of mullite, 30-40 parts of silicon dioxide, 20-30 parts of ferric oxide, 15-20 parts of graphite, 5-15 parts of river sand,25-55 parts of purified water, 5-15 parts of sludge and 5-10 parts of polyacrylamide. The invention further provides a preparation method of the foamed ceramic. The prepared foamed ceramic has good compressive strength, heat conductivity coefficient and closed-pore rate. 本发明公开了一种利用钢渣制备的泡沫陶瓷及其制备方法。属于建筑材料技术领域。包括以下重量份的原料：钢渣100-150份、莫来石25-30份、二氧化硅30-40份、三氧化二铁20-30份、石墨15-20份、河沙5-15份、纯净水25-55份、污泥5-15份和聚丙烯酰胺5-10份，并提供了其制备方法。本发明制备的泡沫陶瓷具有良好的抗压强度、导热系数和闭孔率。
