Polycarboxylate superplasticizer /polycarboxylic acid water reducer

Polycarboxylate superplasticizer /polycarboxylic acid water reducer

Weifang Rebetter Chemical Co., Ltd is a trading company having our own factory,which is located in the Dongcheng Industrial Park of Linqu county, Weifang city, Shandong province.Our factory has a registered capital of 50 million yuan and covers an area of  300 acres. We are a professional industry and trade integrated enterprise engaged in the production, sales and technical services of naphthalene-based water-reducing agents. In 2010, our factory invested 500 million yuan to build an annual output of 300,000 tons of naphthalene-based superplasticizer project. The project adopted international advanced technology and used safe and eco-friendly production equipment. Relying on many domestic authoritative institutions for concrete admixtures, we have hired many senior experts in the fields of R&D, production, and application as technical consultants.

Polycarboxylic acid water reducer is a new developed generation of high performance water reducer, which belongs to high performance water reducer of carboxylic acid graft copolymer.This product has the characteristics of low production energy consumption, no formaldehyde,no production waste and so on. It is an energy-saving and environment-friendly product. All the indicators of the product can meet the technical standards and specifications of high performance polycarboxylate water reducer such as GB8076-2008, JG/T223-2007 and TB3275-2011, and have good adaptability with most cement. This product has been widely used in the key projects such as highway,railway,bridge,port,commercial concrete mixing station,water conservancy and hydropower projects,etc.

This product also has good adaptability to cement, such as water reduction rate of more than 40%, strong liquidity retention ability and so on（high water reduction, high slump retention ability, low alkali content for the product, and it having high strength gained rate).Adding into concrete can obviously improve the workability of concrete and make fresh concrete have excellent liquidity and slump retention performance.

Characteristics:

1.High water reducing ratio: The water reduction rate of concrete is above 40%

2.It is easy to control the production: Controling water reduction ratio, plasticity and air entraining by adjusting molecular weight of main chain,length and density of side chain,type of side chain group.

3.Good slump retention ability.Delaying time of transporting concrete and time of detention at construction site, guarantee concrete pumpability.

4.Good adhesion: Making concrete have excellent workability, Non-layer,without segregation and bleeding.

5.Good dispersion: High fluidity of concrete results in deposing and compacting easily for self-compacting concrete.

6.High strength growth ratio: Greatly increasing early and after strength, reducing energy loss. Reduction of cracking, shrinkage and creep.

7.Wide adaptability: It is compatible with ordinary silicate cement, silicate cement, slag silicate cement and all kinds of blendings having excellent dispersibility and plasticity.

8.Good strength and durability: low lacuna rate, low alkali and chlorin-ion content. Enhancing concrete strength and durability.

9.Environmental friendly: No pollution during production.

10.Low energy consumption and low cost.

Application & usage

The original solution of polycarboxylic acid water reducer can be combined into admixtures with various properties,which can be widely used in the key projects such as highway, railway, bridge, concrete mixing station, water conservancy and hydropower,etc, as ready-mixed concrete, self-compacting concrete, pumping concrete, mass condensate, high mobility concrete, high durability concrete,etc.

Precautions

1. Dosage: According to the type of cement, the temperature of the water, the water ratio to cement ratio, the injection part and the spraying process, the quality requirements, etc., the recommended dosage is 1.5-3%.

2. This product is non-toxic and non-corrosive, but it is forbidden to eat. If it is inadvertent,such as in the eyes or in the mouth,please rinse it with water immediately;

3. When it is used in combination with other admixtures, the compatibility test should be carried out;

4. This series of products should be stored in plastic or stainless steel containers sealed at room temperature for a shelf life of 12 months. Do not mix with other admixtures, rain, and any impurities. If the storage is overdue, the professional engineer can continue to use it after passing the concrete trial test.

5. We provide 24/7 technical service support to solve your worries.
