Products Description

HUAXUAN® KH-207
Huaxuan KH-207 is a product developed to meet the requirements of different concrete slump retention time.Through the optimized design of molecular structure, it has excellent slump retention and extremely high water reduction rate, which greatly improves the plasticity index of fresh concrete and improves its pumping and workability.
At the same time, the strength growth and structural development of hardened concrete are also significantly improved.
The product has low dosage, strong adaptability to various concrete raw materials, and can meet various concrete slump protection requirements under pumping, medium and low slump, long-term transportation, and high-temperature construction conditions.

Product Features

Excellent slump retention: within a certain period of time, the expansion degree maintains a small change, which can meet the slump retention requirements of more than 3 hours or even longer.

It espeicially solves the problems of high powder, high mud, too fast loss in summer, etc.

Water reduction rate: the product has a certain initial water reduction rate, which aims to improve the adaptability of the finished water reducing agent.

Good constructability: Concrete has good fluidity, easy pouring and construction.

Excellent workability: no segregation, no bleeding, which is beneficial to the growth of concrete strength and structural development.

Extensive adaptability: It can adapt to the problems of machine-made sand with high mud content and high powder content, can alleviate the influence of flocculants to a certain extent, and adapt to various cements and admixtures.

Application

HUAXUAN KH-207 is suitable for concrete with high requirements on slump retention, such as mass concrete, long-distance conveying concrete and pumping concrete, especially suitable for maintaining the slump of concrete under long-term transportation and high-temperature construction conditions.

HUAXUAN KH-207 is suitable for various national key projects such as water conservancy, marine engineering, port, transportation, and electric power that require high concrete performance; it is especially recommended for high-strength and high-performance concrete and super-fluid shock-isolating self-compacting concrete.

How to use

DOSAGE
Usually, we recommend that KH-207 and KH-204 are used in combination. 
The ratio of KH-204(WR) and KH-207(SR) is (90%~50%): (10%~50%), and after compounding the dosage should be 0.05%~0.25% of the cementitious material. 
After diluting in proportion, it can be added to the concrete mixer together with water. 

It is better to add 1~4% of the mass of water reducing agent and retarder to adjust the setting time.

INSTRUCTIONS
HUAXUAN KH-207 polycarboxylate high-performance water reducer is usually diluted with water into a liquid with a solid content of about 10%-20% before use.
For example, add water(750 kg) to HUAXUAN KH-207(205 kg) ,and stir them evenly, you will get 1 MT water reducing agent ready to use.
At the same time, other admixtures can also be added to increase product performance.
For example, you can use HUAXUAN KH-207 to prepare HIGH PERFORMANCE PLASTICISING RETARDER.
FORMULA:HUAXUAN KH-204+HUAXUAN KH-207+sucrose+air entraining agent+HUAXUAN-HPMC.
The ratio of KH-204 to KH-207 is 7:3~1:9.
When the daily average temperature is 20 ℃, the amount of sucrose is 1-2% of the superplasticizer.
When the daily average temperature is above 30 ℃, the amount of sucrose is 2-4% of the superplasticizer,and the amount of air-entraining agent and HUAXUAN-HPMC is 0.02% of the superplasticizer.
