Is a high-performance polycarboxylate superplasticizer developed by HUAXUAN HIGH TECHNOLOGY to meet the needs of different concrete slump protection. This series of water reducers have excellent slump retention and extremely high water reduction rate through molecular structure optimization design, which greatly improves the plastic index of fresh concrete and improves its pumping and construction properties. At the same time, the strength growth and structural development of hardened concrete have also been significantly improved. The product has a low content and strong adaptability to various concrete raw materials, and it can meet various requirements for concrete slump protection under pumping, medium and low slump, long-term transportation, and high-temperature construction conditions.
By adding HUAXUAN HIGH TECHNOLOGY�® KH-206 can obtain the following results:
(1) Excellent slump retention: within a certain period of time, the fluidity increases by time, till it increases to the maximum value.
(2) Ultra-high water reduction rate: the water reduction rate is as high as 40% or more;
(3) The concrete has good mobility, easy pouring, and easy construction;
(4) Good workability: no segregation and no bleeding, which is conducive to concrete strength growth and structural development.
(5) Wide adaptability: adapt to various cements and admixtures.
Appearance:light yellow liquid
Solid content:50%
Application:
It is suitable for concrete with high requirements for slump retention, such as large-volume concrete, long-distance conveying concrete and pumping concrete. It is especially suitable for maintaining concrete slump under long-term transportation and high-temperature construction conditions,also it is suitable for various Water conservancy, marine engineering, ports, transportation, electric power and other national key projects that require high concrete performance,especially recommended for high-strength high-performance concrete, super-fluid, earthquake-free and self-compacting concrete.
How to use:
It is recommended to be used in combination with other water-reducing polycarboxylic acid water-reducing agent mother liquor. The ratio of water-reducing mother liquor to slump-preserving mother liquor is better to be (90%-50%): (10%-50%), and the solid content after compounding should be 0.05%~0.25% of the cementitious material.After being diluted in proportion, add it to the concrete mixer together with water,and youâ??ll see better effects when adding retarder of 1-4% of the quality of the water reducing agent.

HUAXUAN HIGH TECHNOLOGY�® KH-204
Is a new version high-performance polycarboxylic superplasticizer. Compared with other high efficiency water-reducing agents,it has the properties of ultra-high water reduction,low shrinkage,low bleeding rate and small avalanche loss.
Ultra-high water reducing rate:up to 40%,particularly significant in high-grade concrete (above C50).In the same condition,it costs less material to get the same effect.
Excellent plastic retention:
Excellent plastic retention performance: Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, the product has high dispersion and can maintain this performance for a long time.
Good early strength and strengthening effect: under the same conditions, the concrete mixed with this product has a higher early strength and strengthening effect than other types of superplasticizers.
Significantly improve the durability of concrete: The product has a low alkali content, and because itâ??s an air-entraining type high efficiency water reducing agent, it significantly reduces the alkali-aggregate reaction of concrete and improves the freeze-thaw resistance of concrete.
Stability: The concrete shrinkage and creep properties will be effectively improved after adding the product,in the meanwhile, it gains a good stability, so there are lower risks of cracks.
