Special advantage

1.Technical features: The integrated solution of "environmental protection coagulant" and "energy saving intelligent brick making machine and international patent intelligent mixing system" of Qingdao Enji Road is adopted to treat industrial solid waste and construction waste, which has the following unique advantages:

Many: the absorption rate of industrial waste and construction waste reached 91.6%;

Fast: the road can pass in 2 days after laying and rolling forming, and the strength reaches C30 in 10 days; Patented brick making machine produces 18900 standard bricks per hour;

Good: roads and building materials meet or exceed the relevant national quality standards;

Province: large amount of solid waste, small amount of "environmental protection coagulant" (0.2%); Brick machine single warehouse material supply, covers an area of less, no need to set up steam, sintering kiln, natural open-air maintenance for 2 days; Road laying using mobile mixer batching, feeding, along with the shop along with rolling forming, short construction process, less investment in equipment, fewer construction personnel, high construction efficiency.

4.Test report

The unconfined compressive strength of the road built by Qingdao Engrace Road Company using ferrochrome slag is 33.7MPa in 28 days, which is as strong as C30 cement concrete, but the cost is much lower than that of cement road construction.

The road of Qingdao grace company USES, construction waste, living garbage incineration slag gasification slag, slag, coal gangue, constrained red mud, smelting slag, desulfurization gypsum, tail slag, fly ash, domestic sludge chemical sludge, phosphogypsum, weathering, alkaline soil, such as solid waste, the production of various types of green brick, strength are reaching or far exceed the national standard准。

Grace road environmental protection technology treatment of solid waste, with a large amount of solid waste, low cost characteristics. Detection report shows that the content of chromite slag in environmental protection brick exceeds 90%, strength grade, wear resistance, frost resistance, skid resistance and radionuclide limit. All comply with GB/T25993-20 standard.

Grace Road environmental protection technology to deal with solid waste, the core coagulant content is 0.2%, cement content is about 8%, the comprehensive solidification effect of coagulant on all kinds of solid waste raw materials is very significant. More common avoid burning brick, have intensity tall, antifreeze sex is good, the characteristic that does not have 2 times pollution.
