HS:*********0 naphthalene sulphonate formaldehyde-based, high range water-reducing ***** sulphonate-type. Its main component is naphthalene sulfonate formaldehyde condensation substance. It is non-air entraining high-efficient water reducing agent with excellent comprehensive properties for concrete projects. A high range water-reducing admixture that produces a low water/cement ratio giving high performance concrete. Promotes high slump, extremely flowable concrete that achieves high strengths while providing superior workability and pumpability. Main indexes 1.Physical item: * Sodium sulphate:5%max *0%max *0%max (three kinds) ** Solid content: light browner powder *** Appearance: *2%min **** Chloride: 0.3%max ***** Water inside: 7%max ****** Ph: 7.**8.5 ***** the effect of the concrete as following: * ****0% of cement can be reserved under the condition of the same caving in and same strength ** Non-poisonous, odorless, non-flammable and non-corrosive to steel bars. *** Suit for blend for the C**-C*0（*2MPA**0MPA ）concrete **** Degree of collapses(Degree of fluidity): **0 mm- **0 mm ***** Reducing ratio *8%**0% ****** As the condition of the material and the climate where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by ****8% when it is mixed with reinforced concrete at 0.**1.2%. Statistically, compression strength on the lst day, the 3 rd day and the *8 th day after single application is increased by *****0%, and ****0% respectively when it is added at standard blend dosage. The compression strength, tensile strength, buckling strength and modulus of elasticity will be improved. 3. Scope of application * Apply to Natural curing concrete and aerated concrete ** Apply to compound lean concrete and high strength concrete *** Apply to all types of Portland cement 4. Application method * The quantity scope to be mixed:0.4－1.2ï¼… of the weight of cement, better performance will be given if the scope could be controlled by 0.**0.8%. ** The N-series High Range Water Reducers could be 1. directly mixed in cement 2. compounded to solution before mixing with water added to cement.
