Science and Practice of aerated concrete block equipment proved: the traditional raw materials and part of the "three wastes" can be used as raw material production of aerated concrete. Lime, power plant fly ash, coal gangue, blast furnace slag, Portland cement, quartz sand (river sand, river sand), gold tailings powder, glass powder tailings, phosphogypsum, etc., and a variety of natural and processed in line with the requirements of technical regulations After the waste can be used in the production of aerated concrete equipment. First, consider the use of these materials as well as the quality of the economic effects of the choice of production method of raw materials, most of these materials as physical - chemical properties of instability, its quality is poor, so they ratio of binder to frequent changes. Therefore, the process is not easy to stabilize, companies do not scrap and difficult to produce quality products. Lime is due to our production process is not perfect, the total level of lime lime production in less than 50%, so that part of the production is difficult to achieve stable production companies. And other raw materials must be prepared to decide treatment, a mixture of a series of raw materials for the selected route depending on the variety. Should be based on reasonable technical and economic investment to improve the uniformity of the mixture, stimulate and enhance its activity, and can not copy the photo sets, Yihuhuhuapiao or random simplified. In recent years the national production of aerated concrete equipment doubled almost continuously, and the product quality is still unsatisfactory, little progress. This year I have the opportunity to go northwest, east, and north China for research, some of the quality of production of aerated concrete equipment is to be commended. And national standards GB/T11968-1997 "aerated concrete block device" requirement falls far short of even the least some enterprises are lack of raw materials, means of detection, the production process can be streamlined to simplify the preparation and control of raw materials. Hard to believe that these products manufacturers is how to enter the market, since the negative impact they are worrying. So take advantage of changes in technology must have a large technical and economic analysis and investment, strengthening technical processes and methods of treatment of "three wastes" as raw material or raw material quality. Increase essential preparation equipment raw materials, strict control of process parameters, deviation must be promptly corrected, in order to ensure stable production of aerated concrete equipment.
