Hollow Bricks, Perforated Bricks and Standard Bricks
The serial technology of JFS slag activated excitation is developed by the Institute of Science and Technology of Building Materials Beijing so as to accept the unprecedented challenge in the wall material market, as the state policy of popularizing new wall materials is being executed and clay bricks are being eliminated from the market all over the country. It is designed to produce hollow blocks and free-burning bricks, making wide use of materials such as wet ash in power plants, dry ash, hybrid ash, boiler slag, spontaneous combustion coal gangue, mountain flour, sand, haydite, mine tailings, scoria, steel slag, carbide slag, water-granulated slag, wind-granulated slag, dry slag, smelting slag, sulfuric acid residue, phosphate fertilizer slag, caustic sludge, laterite in aluminium manufacturers, electrolytic copper slag, stonework waste, potsherd, waste brick powder, construction waste, etc( among which one or two kinds are enough). The products have special features such as lightness, low cost and high strength; moreover, the production process is free of baking and steaming, so that it will not bring about secondary pollution. Also, they are better than clay bricks with regard to anti-permeability, heat and thermal insulation property and construction property (e.g. it is easy to notch due to their good toughness).

ⅠTechnical Superiority
Building material production, especially wall material production, is a great resource consumer, so the manufacturers?major concern is how to control cost and improve their capability in the market competition.
The technology of JFS activated excitation just rises to meet such a demand. The production process can be adulterated with a large amount of local waste resources which are urgently needed to be dealt with, such as fly coal ash, boiler slag, sand, crushed stones, etc. Therefore, it may save freight, reduce cement consumption and cut down raw material cost by about 30%. Besides, it can be exempted from taxation.
(Refer to the contrast table of normal production and the technology of JFS activated excitation in terms of raw material cost)

Ⅱ Product Superiority
The products produced with this technology are of multi-function and outstanding performance. They are also pretty good in terms of thermal insulation, sound insulation, fire-proofing, lightness, earthquake-proofing, firmness and nice appearance. Thus, they are really a good choice for high-performance modern residences, which may become lighter, more energy-saving and beautiful.
Ⅲ Equipment Superiority
1. The products are produced according to the international standard, which have also reached advanced national standards. Technology such as constant vibration, frequency conversion and braking is put into practice in the production process. Apart from this, after vibration and energy consumption will stop immediately the machine is turned off.
2. Key parts of the equipment are made with fine workmanship according to fatigue-resistant design, which may meet users’ demand of continuous multishift production.
Ⅳ Technical Indexes
The test result from the State Building Materials Test Center shows that all the technical indexes of this product have reached the national standards. According to the local materials, resources and different application of products, various strength grades demanded by the designer can be made, such as 1.5Mpa, 2.5 Mpa, 3.5Mpa, 5.0Mpa, 7.5Mpa, 10.0Mpa, 15.0Mpa, etc. in the methods of assumed unit weight, overweight substitution, empirical formula, etc. on the basis of the economical and practical principle.
Ⅴ Technological Process

From the technological viewpoint, the technology developed by our institute, which utilizes fly coal ash and industrial waste to produce new serial building materials, boasts of its advancement and highly-automatic equipment. Thus, it demands less investment in fixed assets, but offers the investors higher production efficiency and more economic returns.
