We are offering sodium naphthalene sulfonate formaldehyde etc. We offer water reducing concrete admixture, naphthalene concrete admixture. Description jk-01np is a high range water reducer, high concentration naphthalene-based superplasticizer, also named naphthalene sulfonate formaldehyde condensate (nsf), snf, pns and fdn etc. jk-01np (na2so4�5%) contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable. Thus, it meets the requirements of chemical admixture specifications for concrete: comply with astm c 494, type f. Astm c 1017, gb8076-2008 and gb50119-2003 etc. uses 1.jk-01np possesses the features of no retarding, no air-introducing, superplastic high water-reducing and strength enhancing. It has no chloride, low alkali content, low sulphonate, and high purity. It can be widely used in different concretes with less dosage and easy to use. 2.jk-01np can be applied to make flowing, strong or steam-curing concrete. The minimum working temperature can be as low as zero centigrade degree. In steam curing, concrete with superplasticizer has to be strong enough before heating. The steam curing specification has to be pre-tested. It is particularly used as base material for compound admixtures. 3.it can prevent from the alkali-aggregate reaction because of the biggish alkali reactivity of aggregate or the alkali-aggregate reaction in the moist environment. advantage 1. high water-reducing rate: jk-01np can reduce water 20-30%. It has features of superplasticizer, effectively increases concrete fluidity and reduces water penetration and segregation and improves the encapsulation force of the concrete with reinforcing steel bar. 2.strengthening: given the same amount of cement and slump requirement, this product with the dosage 0.5-1.2% can increase the concrete early strength and reinforced effect by 50-100%, 40-70%, 25-60% and 20-60% on day 1, 3, 7, and 28 respectively. 3. high applicability: it can be used with different variety of cement. It is compatible with other admixtures. 4. low sodium sulfate content: the aqueous solution has no crystals in winter, which can avoid pipeline congestions when jk-01 np applied. It is suitable for automatic working. 5.effective durability: it can modify the structure of concrete and increase the property of anti-seepage, anti-freezing, and carbonization. 6.easy to use: it can be added directly or used after dissolved in water. It can be used for different working condition and concrete mixer.

We are offering offer amino concrete admixture, plasticizer, sulphonate concrete admixture. Description jk-03 asp is a high range of water reducer which is a modified amino sulphonate and organic compounds with retarding effect. It contains no added chloride and meets the requirements of chemical admixture specifications for concrete: gb8076-2008, gb50119-2003. It complies with astm c494 type f specifications. uses 1. jk-03 asp has the advantages of no air-introducing, low dosage, low slump loss, no chloride and no sodium sulfate crystal. At normal condition, it can be prepared for c50-c80 high strength and high-performance concrete. 2. it is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation. 3. applicable to the preparation of a plastic security requirement of commercial concrete, high-fluid concrete, retarder or super-retarder concrete, self-compacting concrete, mass concrete etc. 4. applicable in concrete precasting and steam-curing for both industrial and civil construction project. 5. available for base material for compound admixtures. It can be mixed with naphthalene-based superplasticizer which can achieve better water reducing rate and high strength performance. advantage 1. low dosage: 0.5-1.5% with high water reducing 15-32%. 2. low slump loss: it can satisfy the requirement of long time and distance transportation. It is ideal for commercial and pumping concrete. 3. effective durability. It has the property of high volume stability, anti-seepage and anti-freezing. 4. low alkali content: it can prevent alkali-aggregate reaction. When it is used in winter, there is no crystal. 5. jk-03 asp can make high-slump flowing concrete. It allows concrete to be produced with very low water/cement ratios at low or normal slumps. 6.wide applicability. It can be used with different variety of cement. Compatible with portland cement, normal portland cement, portland slag cement, fly-ash cement and portland pozzolanic cement etc.
