Pinghu City supplies wear-resistant material manufacturers 2015 high-strength wear-resistant material price list

Ordering phone number:
High-strength wear-resistant material is a new type of inorganic composite building material. It has the characteristics of simple and fast construction, impact resistance, erosion resistance, high temperature resistance, thermal shock resistance, good integrity, easy repair, low price and convenient transportation.

3. Scope of application
It is suitable for wear-resistant layers in concrete structures with wear-resistant requirements such as slag ditches, ore chutes, and lower hoppers.
4. Construction equipment and tools
Forced concrete mixer or self-falling concrete mixer. Vibrator or plate vibrator.
5. Construction Preparation
● Concrete Base Treatment
Clean the surface of the foundation, and there should be no gravel, laitance, floating ash, release agent and other debris. Any loose parts on the foundation surface should be removed.
For concrete foundations that are vertical or have a large slope, steel bars for plum-shaped nails should be arranged, with a length of 100 m, a shape of 10 m, and a spacing of plum blossom nails.
The foundation surface should be fully moistened hours before construction.
● Steel base treatment
Remove rust from the surface of the steel plate and remove oil stains and other debris.
Arrange plum blossom nails (the form is the same as above).
● The mixer should be as close as possible to the construction location to facilitate continuous construction. The water used for mixing should be clean water. Sewage, waste water, and water containing impurities are strictly prohibited.
6. Mixing
● Pour the high-strength wear-resistant material into the mixer, then start the mixer and dry mix for several minutes.
● Pour the weighed water (water consumption is about %) into the blender and stir for ~ minutes. When using a self-falling mixer, the mixing time should be appropriately extended. The slump out of the tank should be controlled between.
7. Construction
Before starting construction, the residual moisture on the surface of the foundation should be removed, and the prepared concrete interface treatment agent should be evenly applied on the surface of the concrete foundation with a brush, and then poured immediately while it is still wet. construction. (See the instructions for use of the concrete interface treatment agent for details)
Pour the high-strength wear-resistant material into the formwork, and then use a vibrator to vibrate. The vibration time should be based on the surface of the high-performance wear-resistant material being slurry. If the thickness of the construction layer is thin and it is not suitable to use a vibrator, plastering construction can also be used. During construction, attention should be paid to patting and compacting until the surface is slurry. Then perform calendering treatment to ensure smoothness and no floating slurry on the surface after construction.
The time from adding water and stirring the high-strength wear-resistant material to the completion of vibration molding should be controlled within an hour.
8. Maintenance
Maintenance measures should comply with the relevant provisions of the "Code for Construction and Acceptance of Reinforced Concrete Projects".
