Product Description:

Naphthalene Sulfonate Formaldehyde (PNS)
(Na2SO4 ≤18%)


Description
PNS, a high range water reducer with no air entraining component, is also named as Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.. It complies with chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017.

Application
1. PNS is suitable to make autotrophic concrete, steam curing concrete, steel concrete and prestress concrete, all of which are made mainly of portland cement.
2. PNS is applicable in areas with the daily lowest temperature of 0
and for making concrete which requires high fluidity, high strength or steam curing.
3. PNS can be used to make C80 concrete with slump loss between 50mm and 70mm, or C60 concrete with that between 180mm and 220mm.
4. PNS can be used as a raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.
5. PNS is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.

Features and Benefits
1. High water reducing rate: over 20%.
2. Saving cement without sacrificing slump retention and strength.
3. Good flowability.
4. Early and post strengthening ability.
5. Great compatibility with various types of cement.
6. Improved Compactness: it develops a better pore structure and makes the concrete more compact. It produces high durable concrete of which the anti-infiltrating index is beyond P18.

Uses and Dosages
It can be added during mix or after mix, while the afterward approach is preferential.
Dosage normally ranges from 0.5% to 1.0% by weight of cementitious material, while the recommended dosage is 0.75%.

Package
It's packed in woven fabric bag with plastic liner. Net weight: 25kg.

Q:The type of mortar and composition of the mortar material has any characteristics
Hello, I see your question for a long time no one to answer, but the question expired no one answered will be deducted and your reward points will be confiscated
Q:Construction site masonry mortar requirements M5 should be how to configure how the calculation is very urgent Thank you, ah
Cement 32.5 (general) M5 mix ratio (weight ratio): cement: sand = 1: 5.23. Each cubic meter of brick masonry, the need for M5 cement mortar is 0.238m. of which 67.59Kg cement; sand 354Kg (0.26m3).
Q:According to the different parts of the building, how to choose mortar mortar?
the surface layer in order to obtain a smooth, smooth surface effect Material selection layer of plaster surface role and requirements are different, each layer of the choice of mortar is not the same At the same time, the characteristics of the base material and engineering parts of different mortar technical performance requirements are different, which is the main basis for the choice of mortar type Cement mortar is suitable for wet or strong requirements of the higher parts; mixed mortar used for indoor bottom or middle or surface plaster; lime mortar, knife knife gray, paper ash used for indoor middle or surface plastering Mixed concrete mortar for concrete base For the wood substrate and the surface layer, multi-purpose fiber material to increase its tensile strength to prevent cracking View original post & gt; & gt;
Q:Cement mortar label M5, M7.5, M10, C20, C25; cement grade C15, C20, C25, C30, etc., are used to which stage of the building
Mortar labels are M. M. M7.. M. M12.. M. M. M. M. M40 several. Mortar according to the use of masonry, plaster, seams several, has nothing to do with the label. It must be said that the blame side of the uncle installed Jiao fat scorpion reckless words, can only be said that the high need to use high mortar strength of the place, and vice versa, really not very good explanation. C. C. C. C30 concrete graded cushion useful mortar is also useful C15 concrete, pile cap and so the best use C30 beam with C25 But this is not to say that this is the same, or depends on the parts you use, Its weight, the required strength and so on
Q:How to distinguish between concrete and hard base in the quota and how the filler base is different
Hard base layer refers to the structure of concrete components, filler material base is the base material of soft materials, such as slag insulation layer of material, cement mortar for different layers should be calculated separately, not hard base. Filling material: the roof of the insulation layer, looking for slope and other soft, light and soft material laying of the structural layer, play insulation, looking for slope, heat and other effects, in doing this leveling layer is called in the filling material The Hard base: such as prefabricated panels, castings and other forming, hard grass, in such a level to do leveling layer on the cement mortar on the hard base.
Q:Waterproof engineering should be arranged at what time to do the best?
If it is home decoration in the kitchen and bathroom waterproofing is done after the water and acceptance, paste the wall tiles before doing.
Q:Whether the mortar waterproofing agent needs to be sampled for inspection
need According to the specification, the admixture of the approach must have the certificate and the product instruction manual, and then need qualified laboratories according to the proportion of the manual, the trial test, the performance is qualified before allowing the use of construction
Q:Polystyrene insulation mortar insulation in the external walls. Foreground will be how,
According to the provisions of the document No. 65: civil building insulation materials used to ridicule the tank waste Intuit Biao Shizha sound burning performance for the A-class material. Polystyrene insulation mortar market prospects are not very optimistic.
Q:In the construction materials, 1: 1: 6 cement mortar concrete, in the end is the volume ratio or quality ratio? The answer to this question after the search is different.
I expect a correct answer, not guess, the answer is best to have some evidence of the source, thank you learn trace Yang asked you: 1: 1: 6 cement mortar concrete? Is not the word wrong, there is this? (In the end is mortar or concrete) Question is wrong, is 1: 1: 6 cement mortar A: 1: 1: 6 is mixed mortar, is the volume ratio
Q:Bathroom wall brush flexible waterproof, stick wall bricks easy to fall off after it? Is not tiling cement to add 901
Paste before, brush twice 108 glue, and other plastic into a transparent and then posted on the brick all right!
