Naphthalene superplasticizer
Characteristics
Applicability
1, major components of this product is β -naphthalene sulfonate formaldehyde.
2, with strong dispersion, enhancing the effect of water significantly reduced, and its significant role in early strength. It can speed up turnover of the template, speed up the progress of the project to shorten the construction period. As early as applicable, and performance requirements of high-strength concrete and other increasing strength, improving the long-term performance of concrete.
3, can significantly increase concrete slump to improve mobility. Applicable to commercial concrete, pumping concrete, the fluidity of concrete and grouting materials.
4, does not bleed air. Aplicable to concrete in steam conservation conditions and various grades of natural concrete.
5, no corrosion of the reinforcement. Applicable to the prefabricated cast-in-place concrete, reinforced concrete, prestressed concrete in all types of projects. 6, has a good compatibility for portland cement, ordinary portland cement, slag cement, fly ash portland cement.
Main Features
Quality Index
1, the product has powder, liquid. Powder shows brown yellow and liquid shows dark brown, non-toxic, odorless, non-flammable.
2, content range 0.4-1.5%, recommended amount of 0.75% (liquid in solid content).
3, when added recommended amout to the concrete content:
Cement while maintaining the same dsage and slump, the water reducing rate by up to 18%, improve 1d concrete compressive strength by 50-90%, 3D by 40-80%, 28d by 25-40%, and there is still growth in the late strength.
While maintaining the same circumstances on water-cement ratio and water consumption, can increase concrete slump for more than 100mm.
While maintaining slump and compressive strength in the same basic circumstances, can save more than 15% of cement.
Be able to significantly enhance and improve the concrete durability and other mechanical properties.
Usage and Notes
1, Intermingled quantity range of 0.4-1.5%, 0.5-1.2% for the use of content, when used in accordance with project targets and select the appropriate amount of raw materials.
2, powder products better match the solution, can also be used directly, but must ensure uniform mixing of concrete.
3, if the use of this product or stagnation of water after the introduction of mixed uses, the reduction of water, better dispersion.
4, the products with other types of mixed use of concrete admixtures. with fly ash, ground slag mixture together, such as "double-doped, " but should be based on the content of the total cementing material.
5, in the initial use of the product or changing varieties of cement should be used in accordance with the scene of raw materials and construction with the need for concrete, according to test results than with the correction of construction to guide construction of mixed use.
Packaging, Transportation and Storage
1, powder using a plastic bag lining, outer woven bag packaging, bag net weight 25kg ± 0.13kg; Liquid plastic drums, steel drum packaging, sealing requirements to prevent spills or evaporative drying, but also can transport tankers.
2, transport to guard against the event when the powder sharp objects to prevent damp-breaking package. If moistured can be made of the solution, does not affect the results.
3, this product should be kept in ventilated, dry warehouse in the exclusive storehouse, valid for one year, more than valid after passing testing can still be used.
