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.
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).
Sodium Lignosulphonate ( lignosulfonate ) water reducer are mainly for concrete mixture as water-reducing additive. Low dosage , low air content , water reducing rate is high ,adapt to most kind of cement. Can confected as concrete early-age strength enhancer , concrete retarder , antifreeze , pumping aids etc. Nearly no precipitate product in the liquor additive which is made from The sodium lignosulphonate and Naphthalin-Group High-Efficiency Water Reducer .The sodium Lignosulphonate is fit for apply to building project, dam project, thruway project etc.
The Sodium Lignosulphonate is economical one.
We offer fully automatic Stationary & Mobile Concrete Mixing Plants to produce homogenous mixture of aggregates, sand, cement, water, additive etc. for construction of buildings, bridges, roads, canal, dams and other concrete construction projects.
Our Concrete Batching Plants are with Single integrated PLC based touch screen power and control panel with LCD display. The panel is with in built serial printer interface and power full recipe management.
All Concrete Batch Plant are equipped with separate electronic weigh batching system with PLC based controls for aggregates, cement, water and additive.
