RTN-B Efficient Concrete Pumping Agent

I. Applicability

It is applied to ready-mixed early-strength pumping concrete, ultrahigh pumping distance commercial concrete, reinforced concrete, prestressed reinforced concrete, flyash concrete, waterproof concrete, bulked concrete, road concrete, high strength concrete and so on.

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 18%, if RTN-B pumping agent is added. Also, it can remarkably improve the workability, pump ability, intensity, impermeability, anti-freezing, anti-carbonization etc.

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