RTN-H Delayed Coagulation Efficient Water Reducer
I. Applicability
It is applied to ready-mixed pumping concrete, commercial concrete, bulked concrete, reinforced concrete, large-fluidity concrete, roller compacted concrete, concrete of bored piles etc.
II. Main performances
1. This product is copper brown liquid or brown powder with a dense of 1.16±0.02g/ml. It is non-toxic, odorless and incombustible, does not corrode the steel.
2. Add RTN-H water reducer with recommended intermingled quantity into the concrete. Its water reducing rate is about 10%.
3. While maintain the same proportion of water and ash, this product can increase the slump from 90-110mm to 200-220mm.
4. The product is applied to various common portland cement, portland slag cement and 42.5-level Ⅱportland cement for producing commercial concrete with a intensity of C30 and under C30.
5. Add proper product into the concrete, so as to improve its intensity, impermeability, anti-freezing, anti-carbonization etc.
6. Select proper intermingle quantity according to different temperatures, transportation distances and so on. It can be used for the whole year.
7. This product has quite good compatibility, while using with U expanding agent, flyash, GGBS etc.
