Naphthalene Based Water Reducing Agent for Concrete
Description
Sodium Naphthalene Sulfonate SNF for Concrete Admixture High Range Water Reducing Agent (SNF/FDN/PNS) has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete and precast members with early strength and high strength requirements, can comprehensively improve various properties of the concrete, and is widely applied to highways, bridges, dams, harbors, tunnels, electric power, water conservancy as well as industrial and civil architecture, steam-cured and naturally-cured precast members and so on.
Technical Feature
● 2. Higher slump with lower water / cement ratio.
● 3. Flowable & pumpable concrete with improved rheology.
● 4. Homogeneous, honey comb - free, dense concrete.
● 5. High strength due to reduced water / cement ratio.
Application
a).Widely used in precast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc.
b). Suitable for preparation of early-strength, high-strength, high-anti-filtration and self sealing&pumpable concrete.
c). Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak heat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.
d). Compatible with Portland cement, normal Portland cement, Portland slag cement, flyash cement and Portland pozzolanic cement etc.
Because of the high dispersion force and low foaming characteristics, SNF has also been widely used in other industries as Anionic Dispersing Agent. Dispersing agent for disperse, vat, reactive and acid dyes, textile dying,wettable pesticide,paper,electroplating, rubber, water-soluble paint, pigments,oil drilling, water treatment,carbon black, etc.
