Due to the high glass content of water slag, its physical characteristics are fragile and difficult to grind. The higher its specific surface area is, the higher the power consumption of grinding it to a certain extent in unit time is. The use of the European version of SMMVIK Machinery's pulverizer can improve the power consumption of fine grinding, so that the fly ash water slag can be used, especially for high-rise buildings, dams, airports and other large projects with high requirements.
SMMVIK Machinery's water slag processing European version mill product advantages:
1. The fly ash water slag with high activity index can be added to concrete to replace cement in equal amount, and improve the comprehensive performance of concrete.
2. When fly ash water slag is mixed into concrete, it can reduce the volume expansion cracking of concrete caused by the thermal reaction of sand and stone in concrete.
3. There are more ettringite crystals in the fly ash water slag micro powder, which can reduce the porosity of concrete, reduce the penetration of chloride ions, and form an anti-corrosion protective layer for reinforcement.
4. Reduce the content of tricalcium aluminate and soluble calcium hydroxide in cement, reduce the workability such as erosion loss due to sulfate, improve the late strength of concrete, and have good durability, corrosivity and wear resistance.
5. The concrete is made by mixing fly ash, water slag and fine powder with cement, stone and sand. It has the advantages of high late strength, low hydration heat of cement, good abrasion resistance and good bond with reinforcement.
During water slag grinding, a small amount of fly ash and limestone can also be added. During the grinding process, a small amount of additives can also be added to eliminate the adhesion and aggregation of fine powder. It can accelerate the material grinding process, improve the grinding efficiency, improve the quality, and reduce the power consumption per unit of grinding, playing an auxiliary role in material grinding. The price of grinding aids is relatively high, which can reduce power consumption. Since the input of coal gangue, fly ash zeolite and other easily grindable materials in the mill is conducive to increase production and reduce consumption, the cost of the fly ash mill can be effectively controlled, and it is a mill product suitable for investment.
