Oil well cement additive water reducer concrete
Ketone aldehyde condensation compound superplasticizer is a green and high range water reducer
which was developed by Qingdao Hongsha polymer materials Co., Ltd.
And it neither pollutes the environment nor causes people serious harm.
Specifications: | |

In 90 min lose 10-20% | |
Function | Observably improve the freeze-thaw resistance, impermeability and sulfate resistance of concrete, improve the other physical properties of concrete
|
Widely used in the concrete | Fluidized plasticizing concrete, nature Conservancy-steamed concrete, waterproof Concrete, anti-freeze-thaw durability of concrete, anti corrosion Marine Concrete of sodium sulfate, as well as reinforced, prestressed concrete,good workability and cohesive quality |
Others | Non-toxic, non-ignitable ,non-corroding , without sodium sulfate in the winter |
Usage:
1.Through the experiment to find the best dosage, compliance dosage is 1.5-2%.
2.Joins together with the mixing water in concrete. Then after the addition it can also be used.
3.The concrete mixed with this project should be extended by adding 30S.
4.As the water reducing rate is larger, before initial setting time of concrete,the surface bleeds yellow pulp that is a normal phenomenon. Before the final setting of concrete or after the concrete on the strength, the color will disappear. With water conservation will be to make color fade faster, that do not affect the internal and surface properties of concrete.
• High water reducing rate can up to 15-25%.
• Save cement 25-30%.
• Non-toxic,non-ignitable and non-corroding.
• Without sodium sulfate in low temperature.
• Good workability and cohesive quality.
