    CSA Concrete Repair Material is a high performance blend of rapid set hydraulic cement and quality aggregates. When mixed with water CSA Concrete Material produces a workable, high quality concrete material that is ideal where fast strength gain, high durability and low shrinkage are desired. CSA concrete repair material is non-metallic and no chlorides added.

Strong Point

1. Dry-shrinkage ratio is less than 0.04%.

Portland cement concrete has long hardening time, and so dry shrinkage is very low. If the shrinkage rate of repair material is too high, the original concrete and the CSA repair concrete may have different load-bearing capacity which cause hollowing or split-off.  After decades of delving, finally we find the most suitable mix proportion to get a talent concrete repair material which can develop a micro expansion and low shrinkage. These properties can make the repair material combined with the original concrete surface strongly; most of concrete repair materials in market currently can not reach.

2. Bond Strength ≥1.5Mpa.

Only the original concrete and repair material have solid combination, the concrete repair can achieve the perfect effect. This requires repair materials have higher tensile bond strength. The addition of polymers certainly ensures this purpose, meanwhile improving the flexibility of the repair material.

3. Avoid cracking, falling off and breaking.

4. Freeze resistance, impermeability, good corrosion resistance.

Scientific ternary system let our repair material have a micro expansion, low water ratio, the addition of polymer improve the density of the repair material and antifreeze, impermeability and corrosion resistance properties.

5. Polymers and the addition of quartz sand used as aggregate material greatly improves the wear resistance of repair materials.

6. High early strength.

Its compressive strength can reach 3.5Mpa within 6h, 35~50Mpa after 28days.

7. Easy to use.

The maximum diameter of aggregate in repair material is below 1.5mm; fully apply to all kinds of thin patch. According to the patching thickness, 1.5~25mm size aggregate can be added as well to increase the strength of repair material.

8. High performance and competitive price.
