naphthalene sulfonate formaldehyde concrete admixt

HSN naphthalene superplasticizer FDN Implementation of standards:GB8076-2008Brief introduction:The main components of HSN naphthalene superplasticizer are β naphthalene sulfonate formaldehyde condensate. It is a type of non-air-entraining and water-reducing admixture. Its form is the powder or liquid. The agent is applied to various of cement. It can improve the workability of concrete,that is widely used to highway, railway, bridges, tunnels, power plants, dams, high-rise buildings and other projects.Technical Indicators:Outward appearance: pulvis: brownish-yellow powdered; liquid: brownish-yellow viscous fluid. Solid content:pulvis≥92%;liquid≥40%. PH value (5% aqueous solution):7 9. Content of sodium sulfate: pulvis16 18%;liquid7 9%. Fluidity of cement paste: ≥200mm. On condition that maintaining the water-cement ratio unchangeded,it can increase the concrete slump over 10CM. When maintaining the concrete slump unchangeded, the water reducing rate can be up to 12 20%. The product has Significant hardening accelerating and enhancement effect to concrete which strength improves 15 40%. All-roundly improve the other mechanical properties of concrete. Under the same strength, it can save cement of 10 20%. No the effect of corrosion of reinforcing steel bar.Usage :pulvis:0.5 1.0%,compliance dosage is 1.0%;liquid:1.0 2.0%, compliance dosage is 1.5%,According to the level of concrete enhanced, dosage can be appropriately increased. Every batch of goods,test achieve user’s requirements before they can use up.Packag : pulvis: Packaged in polyethylene-lined fiber including plastic bag containing25 kg or 40kg of product; liquid: In iron drums containing 250kg of product.Technical Service: The company's technology department provide technical advice to the user at any time,who will accord to the construction required to adapt to user for all kinds ofthe strength grade concrete producting products.We can guide at the spot to meet customer requirements
