Naphthalene Sulfonate Formaldehyde (SNF)
(Na2SO4 ≤ 5%)
Description
SNF is a high concentrate naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate (NSF), SNF, PNS, etc.. FDN contains no chloride. It conforms to the requirements of chemical admixture specifications for concrete: ASTM C 494, Type F; ASTM C 1017.
Applications
1. SNF is suitable to make autotrophic concrete, steam curing concrete, steel concrete, prestress concrete, etc.
2. SNF is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.
3. SNF can be used to make C80 concrete with slump loss between 50mm and 70mm, or C60 concrete with that between 180mm and 220mm.
4. SNF 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.
Features and Benefits
1. Non-toxic, non-irritating and no corrosion to steel bars.
2. High water reducing rate: over 25%.
3. Strengthening ability.
4. Improving concrete durability and impermeability.
5. Appropriate setting time.
6. Low sodium sulfate content.
7. No crystallization in winter.
8. Good compatibility with various types of cement.
Uses and Dosages
It can be added during mix or after mix, while the latter approach is preferential.
Dosage normally ranges from 0.4% to 1.0% of the weight of cementitious material, while the recommended dosage is 0.5%.
Package
It’s packed in woven fabric bag with plastic liner. Net weight: 25kg.
- Q: The use of cinder and other waste slag production of brick materials to enjoy what preferential policies
- 156), the proportion of raw materials produced in the production of raw materials is not less than 30 % Of the specific building materials are exempt from VAT
- Q: What are the specific specifications of the external wall insulation material re-examination?
- Mainly to see its bulk density, flame retardant and thickness
- Q: Waterproof coating type Ⅰ and Ⅱ What is the difference between ah?
- A lot of waterproof materials, including coatings and coils, are divided into type I and type II or even type III, mainly physical properties of the distinction between the distinction that some of the mechanical properties of the level, and some only show the performance difference, for different Waterproof selection of parts. Such as "JS" waterproof coating type Ⅰ strength and elongation were 1.2MPa / 200%, Ⅱ type were 1.8MPa / 80%, one is low strength and high extension, the other is high strength and low extension, suitable for different waterproof parts The Another example is the infiltration of crystalline waterproof material Ⅰ and Ⅱ type that impermeability level, Ⅱ type impermeability better. Also used in class I and class II, this distinction is mainly to indicate the material morphology or material composition of the different, such as polymer cement waterproof mortar Class I and II said emulsion type and dry powder type. What is the specific performance of the waterproof coating may look at the corresponding waterproof material standards, such as polyurethane waterproof coating is GBT "polyurethane waterproof coating"
- Q: 1 ton of inorganic insulation mortar is equal to how many cubic
- insulation mortar is a variety of lightweight materials for the aggregate, cement as cement, mixed with some modified additives, mixed by the production and mixing made of a pre-mixed dry mortar
- Q: Paste the culture of stone mortar into the construction site after the need to do material re-examination?
- Commercial mortar raw materials do not have to do the re-test, but the factory certificate, factory inspection report, manufacturers send third-party testing reports, invoices and so must be complete
- Q: Now what is the general use of indoor plaster material? Please advise, thank you
- General plaster general plaster used by the material are lime mortar, cement mortar, cement mortar, polymer cement mortar, knife knife ash, paper lime, plaster gypsum, etc
- Q: I would like to check, I would like to ask C. C20 with more than how to check, there are mortar M5 cement, mixed mortar how to check, the need for any material.
- Mortar is mainly sent to the cement and sand; and then to the test unit to fill the next order, indicating the design strength and consistency there are structural parts; if you have added mortar or admixture and the like, to refer to the added material certificate above The best proportion to add, the general inspection when the inspection unit will require a copy of a certificate
- Q: Insulation putty can be used alone as an external wall insulation material? Whether the external wall insulation putty can replace the external wall mortar
- Under normal circumstances need to use with the insulation materials
- Q: What kind of waterproof material is used for waterproofing in basement?
- This need to be based on the size of the basement structure and size to decide, if it is a large underground garage, you can consider the reaction with the dragon sticky waterproof membrane, this material to do the overall performance of waterproof better, not easy to channeling water; and if only home Or Shanghai workers high Ji 薨 wasteland for miles of small supermarkets underground storage room with a rigid waterproof coating on the line, such as the dragon's JS composite waterproof coating ~ ~
- Q: Is a square meter in the number of kilograms of cement how much kg
- 1 bag of cement (standard 50KG actual more than 40) +4 bags of sand can find 3-5 square
