Concrete additives

High range water reducer, Poly naphthalene sulphonate, Sodium naphthalene formaldehyde, Water reducer agent, concrete superplasticizer, Naphthalene sulfonate formaldehyde, Concrete additives, PNS/SNF/FDN/NSF. PROPERTIES AND FEATURES GRADE UNF-5 1. Good effect of water reduction and dispersion 2. Improve the pore structure of concrete and enhance the integrity and density of concrete . 3. Improve the workability and mobility of concrete. 4. Significantly enhance early and late strength of concrete. 5. No corrosive effect on reinforcing steel. GRADE UNF-5A 1. Meet all properties of UNF-5 2. Low content of alkali would prevent Alkali - aggregate reaction of concrete. 3. Suitable for preparation of high strength and performance concrete. APPLICATION GRADE UNF-5 1. Widely used in industrial and civil concrete projects, such as construction, water conservancy facilities, traffic, ports and public works. 2. Widely used in precast and on-site concrete, reinforced concrete and prestressed concrete. 3. Suitable for preparation of early-strength, high strength, high-anti-filtration and self-sealing& Pumpable concrete 4. Used for self-cured and vapor-cured concrete and its formulations 5. Compatible with various Portland cement and its products GRADE UNF-5A 1. Same as the material of UNF-5 2. For making up liquid products regularly used in winter. 3. Suitable for high durable concrete and the AAR controlled concrete.
