Two industrial solid waste products generated by Indian coal-fired power plants, namely pond ash and fly ash, were used in combination with local clay to develop building bricks. The clay were mixed with the two different ashes in the range 10 to 90 wt.%, hydraulically pressed and fired at 1000 degrees C. The fired products were characterized for various quality properties required for building bricks. The properties of the optimal compositions were compared with conventional red clay bricks including the developed microstructures and the comparative study generally showed that te ash-clay bricks were of superior quality to the conventional products.
印度燃煤发电厂产生的两种工业固体废物，即塘灰和粉煤灰，与当地粘土混合用于制造建筑砖。将粘土与两种不同的灰按10%至90%（重量）的比例混合，进行液压压制并在1000摄氏度下烧制。对烧制后的产品进行了建筑砖所需的各种质量特性表征。将最佳配方的性能与传统红砖进行了比较，包括微观结构的发展情况，比较研究总体表明，灰粘土砖的质量优于传统产品。
