Economic Value Of Waste Products Produced By Aluminum Insulation Board
- Jun 04, 2018 -

There are a lot of slag produced in the production process of aluminum insulation board. The aluminum insulation board is just like the cinder in our daily life. It is used as the domestic garbage and has no use value. The large accumulation of aluminum plates is a great damage to the environment. The production waste of aluminum insulation board is of great economic value.

Blast furnace slag powder is a new type of building material developed and popularized in recent years. Water quenched blast furnace slag grinding to a certain fineness, prompted CaO, increased the activity of SiO2, Al2O3, promote the formation of hydrated calcium silicate products, and fill in the aperture of cement concrete, can greatly improve the density of concrete; At the same time, low strength Ca (OH) 2 crystals were transformed into high strength calcium silicate hydrate gel, which significantly improved a series of properties of concrete. The concrete mixed with slag powder has the characteristics of low hydration heat, corrosion resistance, strong bonding strength with steel reinforcement, strong anti-permeability, anti-shrinkage and post-strength. Water slag powder concrete strength is high, has the very good sulfate erosion resistance, resistance to chlorine ion corrosion performance, slump can meet the requirements of various performance concrete, viscosity, adhesion cohesion and segregation resistance performance. In many countries and regions, slag powder has been widely used and its engineering, underwater engineering, road engineering, coast anti-corrosion engineering, large construction projects, etc., thus has broad market prospects.

Water blast furnace slag powder is made from water slag blast furnace slag in the depth of the building materials industry, one of the development and utilization of the results of water slag powder directly replace part of cement concrete, which can reduce the cost of concrete production enterprises, the direct economic benefit; At the same time, setting up fine grinding facilities and directly selling fine powder can improve the economic value of blast furnace slag, expand the use, and generate greater economic benefits.
