Use of coal washery wastes for common brickmaking
The problem of utilizing coal washery wastes to make ceramic building materials can be solved in two basic ways. The first is to use the wastes as raw materials for making ceramic bricks and drainpipes in specialized undertakings, preferably set up very close to the point of origin of the wastes. The second is to use them as effective additives to the basic raw materials consumed in existing brickyards, to replace the traditional materials. Modern brickmaking industry already faces the problems of raising product quality, lowering raw material costs and achieving higher plant performance. One important step in this direction is to optimize the mix composition by introducing correcting additives. Scientific data and plant experience confirm that the range of suitable additives to brickmaking clay can be greatly extended by making use of local industrial wastes. The utilization of coal washery wastes is a very promising means of ensuring the brickyards of plentiful supplies of additives which reduce the rates of clay and fuel consumption. Their use as brickmaking additives lowers the fuel consumption, brings down the firing temperatures and imporves the strength and frost resistance of the products. Coal washery wastes also act as thinners, i.e., they exert a complex influence on the properties of both the clay mix and the finished product. On the basis of VNIIstrom investigations and data from other sources, recommendations have been drawn up on the utilization of fuel-containing industrial wastes as additives in ceramic brickmaking.
