How to use steel fiber wear-resistant castable, and precautions

1. This product is mainly made of high quality bauxite with various high-grade powder, coagulant, expansion agent, corundum, steel fiber and binding agent, etc. It has the characteristics of normal temperature and high temperature strength, small change of line after burning, good thermal shock stability and strong spalling resistance.

2. Mixing equipment, water source and feeding tools must be prepared for construction water, and concrete mixing and conveying needs must be ensured. The mixing equipment should be based on the amount of construction, 300kg~500kg for each mixing, and the effective mixing time should be 6~8min after adding water.It is required that the feeding tool should not send the material to the mold for more than 10min.

3. The cleanliness of the construction water shall meet the national standard for grade ii drinking water, and the water temperature shall not be lower than 10℃ or higher than 40℃.

4. When mixing, each packaging bag weighs 25KG.The whole bag is required to be used for each stirring, not 1/2 or 2/3 etc.

5. When feeding, there is an additive pouch in each package. Be sure to find it when unpacking, and open the additive and add it to the ingredients in this package.

6. The amount of water added depends on the situation of on-site pouring. The recommended amount of water is 6%±2%.

7. During casting construction, check whether the mold equipment is firm and reliable, and ensure that there is no leakage of slurry or cavity. If slurry flow is found to be poor, stop pouring immediately and discard it firmly.

8. If leakage of slurry or cavity is found during construction, the castable body within the appropriate scope shall be removed in time.Repouring.

9. After pouring, the site shall be cleaned in time. During the handover of each construction shift, the mixed slurry shall be used up.

10. After the completion of pouring, the mold can only be removed after natural maintenance for 48 hours. After the mold is removed, the temperature is higher than 35℃ or the environment is too dry.

11. Oven can be carried out synchronously with furnace body.
