FW-40(High range preserbable supurplasticizer)           Products Our product FW-40 is acrylic type polycarboxylate based superplasticizer, which can display high dispersion performance and slump retention time due to steric and electrostatic repulsion effects, which are part of polymer structures. In addition, its excellent dispersion retention time makes it possible to transport long distances, adjust hardening time, and manufacture excellent quality concrete suitable for construction sites.     Advantages - Prevents slump loss of high strength concrete. - Reduces the quantity of cement used and bleeding. - Improves workability. - Decreases heat of hydration and makes it prossible to adjust cement setting and hardening time. - Makes it prossible to transport long distances for a long period of time. (suitalble for ready-mix concrete)     Applications - Briges, very high buildings and structures that require durability and high strenght. - SOC structures including LNG bases, highways, railway, subway construction and tunnels. - Concrete with high contents of fly ash, blast furnace slag or silica fume. - Manufacture of prefabricated, precast and prestressed concrete. - Manufacture of self-leveling con crete.     Specification Form/Color Liauid/Dark Brown Solid Content(%) 40.0±1.0 pH(25℃) 6.0±1.0 Specific gravity(25℃) 1.10±0.05 Viscosite(25℃,cps) 〈500cps Chloride content None
