HSN Sodium naphthalene sulphonate superplasticizer

Name:Sodium naphthalene sulphonate superplasticizer Detailed Product Description: 1, No toxicity or pollution, and not inflammable 2, The water-reducing ratio reaches 12 20% 3, Makes great increase on fluidity This product complies with the national standard of concrete admixture (GB8076-2008) The ingredient of type HSN is naphthalene sulfonate formaldehyde high polycondensate. This product is non air-entrainment high-concentration super high-efficiency water reducing admixture with very good comprehensive performance in the concrete project. With strong dispersion effect on cement particles and high water-reducing rate, this product can save the cement consumption of project and greatly improve the fluidity and workability of mortar concrete; with obvious early strength and enhancement, it can greatly improve the strength of mortar and concrete and have good adaptability to various kinds of cement. It has no chlorides and no corrosion to reinforcing steel bar. It has been widely used in highway, Railway Bridge, high-storey building, port and dock, hydropower project, pre-stressed structure, and other concrete projects.

Under the same , it can save cement of 10 20%.No the effect of corrosion of reinforcing steel bar.Main Technical Performance: 1. Type HSN is divided into powder admixture and liquid admixture. The powder admixture is brown yellow; and the liquid admixture is brownish black. It has no toxicity or pollution, and is not inflammable. 2. The addition of type HSN powder admixture is 0.5 1.0% of cementing material; and that of liquid admixture is 1.0 2.0% cementing material; and the water reducing ratio reaches 12 20%. 3. Under the same water-cement ratio, the initial slump of concrete can be improved more than 10cm when adding type HSN admixture, which makes great increase on fluidity. 4. When the strength of concrete is basically the same with the slump, the cement consumption of concrete can be reduced 10 20% compared with that of the concrete of no admixture. 5. The adding of type HSN admixture can greatly improve the workability of concrete and various mechanical performance, and compressive strength, tensile strength, flexural strength of components, elastic modulus, and long-term strength all have corresponding improvement. 6. Type HSN water reducing admixture has good adaptability to various kinds of cement and also can be mixed with concrete admixture of other types in conformity with national standards. Scope of Application Type HSN water-reducing admixture is widely applied into concrete projects, especially adapting to the following concrete project: flowing concrete, plasticizing concrete, steam-curing concrete, permeability resistant concrete, waterproofing concrete, mass concrete, natural curing precast concrete, reinforced concrete and pre-stressed concrete, green high-strength high-performance concrete and super high-strength concrete. Usage: Addition: The amount of adding type HSN admixture is 0.5 1.0%, the general addition is 0.75% (calculated as the percentage of dry powder to cement in weight, and the liquid admixture should be converted to the weight of dry powder based on the content of solid , and then calculated). When preparing low-grade concrete or adopting slag cement or Portland - pozzolana cement select and use the amount of 0.4 0.6%; while preparing high-grade and pre-stressed concrete, select and use the amount of 0.75 1.0%. Best Method of Adding Admixture To ensure the best effect, we recommend for the users who first use this product or are to change the variety of cement, make necessary concrete trial mix testing for the amount and method of adding water-reducing admixture and stirring time. And in the construction course, control the amount of water-reducing admixture and the amount of mixing water. When porous aggregate is used, it is better to add water and stir and then add water-reducing admixture.
