RTN-Z Early-Strength Efficient Water Reducer

I. Applicability

1. It is applied to on-site and precast reinforced concrete, prestressed reinforced concrete, flyash concrete, and especially concrete for building roads and bridges.

2. It is applied to high-strength, high impermeability, self-compactability pumping concrete and self-flow grouting material.

3. It is applied to naturally cured concrete engineering and products.

4. It is applied to common portland cement, portland slag cement, portland-flyash cement and Portland- volcano cement.

II. Main performances

1. This product is copper brown liquid or brown powder with a dense of 1.18±0.02g/ml. It is non-toxic, odorless and incombustible, does not corrode the steel.

2. Its water reducing rate is over 15%. Also, it can remarkably improve the workability, moisture capacity, intensity, bending strength etc.

3. It is low air entraining, good delayed coagulation and low slump loss.

4. Use 42.5-level common portland cement to make C 30- C 50 high-strength concrete. Use 32.5-level portland slag cement to make C20-C30 concrete.
