Features and advantages

1. Technical features: The integrated solution for the treatment of industrial solid waste and construction waste using Qingdao Grace Road's "environmentally friendly coagulant" and "energy-saving intelligent brick making machine and international patented intelligent mixing system" has the following unique advantages:

More: The consumption rate of industrial waste and construction waste reaches 91.6%;

Fast: The road can pass after 2 days of rolling and forming, and the strength reaches C30 in 10 days; the patented brick making machine produces 18,900 standard bricks per hour;

Good: road and building materials products meet or exceed relevant national quality standards;

Province: a large amount of solid waste is added, and a small amount of "environmentally friendly coagulant" is added (0.2%); the brick making machine is fed from a single warehouse and occupies a small area. Road paving adopts mobile mixer for batching and feeding, and rolling and forming with paving. The construction process is short, the equipment investment is low, the construction personnel are few, and the construction efficiency is high.

4. Test report

The 28-day unconfined compressive strength of the road built by Qingdao Grace Road Company using ferrochromium slag is 33.7MPa, and the strength reaches the strength of C30 cement concrete, but the cost is much lower than the cost of cement road construction.

Qingdao Grace Road Company uses domestic waste incineration slag, construction waste, gasification slag, slag, coal gangue, sticky red mud, smelting slag, desulfurization gypsum, tailings slag, fly ash, domestic sludge chemical sludge, phosphogypsum, The strength of various types of environmentally friendly bricks produced from solid wastes such as weathered soil and alkali slag has reached or far exceeds the national standard.

Grace Road environmental protection technology treats solid waste, which has the characteristics of large amount of solid waste and low cost. The test report shows that the content of ferrochromium slag in environmentally friendly bricks exceeds 90%, and the strength level, wear resistance, frost resistance, slip resistance, and radionuclide limits are limited. All comply with GB/T25993-20 standard.

Grace Road environmental protection technology treats solid waste. The core coagulant is added at 0.2% and the cement is added at about 8%. The coagulant has a very significant comprehensive coagulation effect on various solid waste raw materials. Compared with ordinary non-burning bricks, it has the characteristics of high strength, good frost resistance and no secondary pollution.
