Lignin sulfonate superplasticizer 
 This product complies with national standards for concrete admixtures. 
 The product is modified lignin sulfonate, the Department of powdered low-lead gas-retarding water-reducing agent, are anionic surfactants, absorption and dispersion to cement a role, to improve various physical properties of concrete. Can be re-dubbed in early strength agent, retarder, antifreeze, pumping agent, and mixed naphthalene superplasticizer made of liquid additives have little or no precipitation. 
 Key Features: 
 1. Lignin sulfonate superplasticizer dosage of cement content of 0.20-0.30%, commonly used content is 0.25% water reduction rate of 9-11%. In the appropriate content when compared with the reference concrete strength increased 15-20%, 3 days, 7 days strength increased 20-30% 15-20% 28 days to improve long-term strength has also increased. 
 2. In the water does not change the concrete situation, can increase the flow of concrete to improve workability. 
 3. In maintaining the concrete slump, the same intensity and the reference concrete, can save 8-10% of cement, using a ton of sodium lignosulfonate superplasticizer powder, cement savings of 30-40 tons. 
 4. In the standard state, the concrete mixed with this agent compared with the reference concrete may delay the initial setting time of 3 hours or more concrete and final setting time of 3 hours and delayed the peak heat of hydration more than 5 hours, is conducive to construction and commercial concrete in summer transport and mass concrete. 
 5. Lignin sulfonate has a micro-air-entraining water-reducing agent of, can improve the performance of impermeability of concrete freezing and thawing. 
 6. The agent after incorporation of reinforced concrete and aggregate non-corrosive. 
 Scope: 
 This product is suitable for mass concrete, high fluidity concrete, pumping concrete, concrete products and concrete construction in the summer and there are special requirements for slow setting concrete, concrete piles, concrete pile Shen, hand-dug piles of concrete and a large underground concrete construction, with good economic returns. 
 Usage: 
 1. The weight of cement content 0.20-0.30%, 0.25% of recommended dosage. 
 2. Powder can be added directly to the cement, sand and gravel in the mix, even after the addition of water for mixing, should be extended mixing time, stirring to avoid uneven. Powder can be prepared in advance a certain concentration of the solution to agent in the form to join, but pay attention to the concrete should be deducted from the total water consumption. 
 3. The user when using this product according to the specific construction conditions (construction season, engineering materials, etc.) with reference to the description of the concrete mix to make the necessary tests to get the best results. 
 Packaging, storage and transportation: 
 1. This product is powder, external auxiliary membrane bags, the use of plastic packaging, bag weight 25kg. 
 2. This product is valid for one year, extended by the concrete can continue to use after passing the test. 
 3. This product should be stored in a cool dry place, attention should be moisture proof, anti-damage both inside and outside the bag. If agglomeration, crushing, or dubbed solution to use, does not affect the results. 
 4. This product is non-toxic harmless, the Department of
