sodium lignosulfonate superplasticizer are surfactants. After they are added to concrete, the hydrophobic groups are directionally adsorbed on the surface of cement particles, so that the cement has a negative charge. The cement particles with the same charge are mutually repulsed and dispersed under the action of charge repulsion. The flocculent structure formed by the cement at the initial stage of adding water becomes a dispersed structure, and the free water in the flocculent condensate is released, so as to achieve the purpose of water reducing agent. Therefore, adding wood calcium superplasticizer into concrete can reduce the water consumption of concrete mixture, reduce water cement ratio, improve workability, facilitate pumping and improve the strength, compactness and durability of concrete

PCE Polycarboxylate superplasticizer is the newest generation superplasticizer used for concrete in domestic and abroad.It is based on molecular designs and adsorption capacity of polycarboxylate,we do R&D and successfully produce water reducing and retention type polycarboxylate superplasticizer for concrete. With initiating systerm and reaction conditions,we achieve high adaptability.Comparing with PNS and other superplasticizer, PCE has many characteristic advantages in technology and performance as following: (1) low dosage, high rate of water reducing; (2) keep concrete good slumption retention; (3) good compatibility with cement; (4) small shrinkage of concrete to keep the stability of volume and durability; (5) environmental in production and usage. Base on above advantages.

It is a high range water reducer, high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate SNF, PNS and FDN etc. Na2SO4 has 3 grades:5% 10% 18% for exporting markets,in domestic we also have 3% 23% Na2SO4 content FDN.It contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable.

NSF full name is Naphthalene Sulfonate formaldehyde condensate. Its high purity makes cement paticles with high dispersancy, low foaming, high range water reducing and obvious strengthening so that we can get advantages of accelerating project mould turnover and construction speed, and also saving cement, improving cement mobility and workability. NSF is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing. NSF has a good adaptability to various cements and NSF is no erodent to reinforcing bar and nonpoisonous and pollution-free. NSF has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay, skyscraper, power engineering, industrial civil building, prestressing force component and high range concrete etc. 25kg/bag.

Application It is a powder form polycarboxylate superplasticizer, mannufactured form its liquid. It reduces the cost of packing and transportion. It is specially designed for oversea construction projects. Properties 1.It is the powder form of its liquid product and has the same properties as following: 2.High early strength: Significant increase of early strength and 28d strength. 3.Low slump lose: Great reduction of slump lose. 4.Excellent durability: Reduction of cracking, shirnkage and creep. 5.High water reduction: Water reduction more than 25% according to different application. 6.Environmental friendly products: Non-pollution during production. Test Data-Sheet The test data-sheet for powder is showed as follows.It was obtained according to the China National Standard Method. A.P.O.42.5 Chinese standard cement and dissolved water solution to 20% solid content was used in the following testing. The dosage of liquid(20%) was 1.0% by weight of cement.( equivalent to the dosage of 0.2% in powder). 200kg/drum.

Purpose: According to GOST 24211-91 ?«Additives for concrete?» softener is applied to regulation plasticity of concrete and concern I groups of a class. Action: Plasticity mark P1 up to P5 increases sdditives of softener. After 28 days of drying hardness raises on 30-60% and norms of charge of cement on 1 m3 is reduced on 60-100 kg thus it intended for improvement of otheres building ??“ technical qualities of concrete. Quality parameters are resulted below: Color – colorless Density – 1,16 gr/m3 pH – 8-9 In the additive there is no chlorine.Norms of the charge calculated on the dry rest weight of cement of 0,4-1,0%. Guarantee: Guarantee for 6 month. Packaging on metal and plastic drums, transported in 250 kg metal containers.

Sprayed concrete is a fast hardening material for stabilization and support of structures and for concrete applications without using any moulds. Sprayed concrete is an interaction of man, machine and concrete. Man, personified in the work of the nozzleman, requires technical skills and dedication to the job. The operator must be able to rely fully on the machine and the sprayed concrete material. It is the interaction and quality of these components that finally determines the success of the sprayed concrete application Sprayed Concrete has many advantages Application to any elevations because sprayed concrete adheres immediately and bears its own weight Can be applied on uneven substrates Good adhesion to the substrate Totally flexible configuration of the layer thickness on site Concreting without formwork Reinforced sprayed concrete is also possible (mesh/fiber reinforcement) Rapid load-bearing skin can be achieved without forms or long waiting times. Sprayed Concrete Applications: - Excavation stabilization in tunnneling and mining construction - Slope and trenching stabilization - Protective lining - Concrete repair (concrete replacement and strengthening) - Special lightweight load-bearing structures - Restoration of historic buildings (stone structures) - Sealing works - Construction of swimming pools User Notes: The technical details and recommendations contained in this data sheet are given in good faith and represent the best of our knowledge and experience at time of priting.
