Product Description
ZT-2Set-retarding, water-reducing agent can apparently slow down the setting of cement. It can lower the heat produced by early cement hydration, cut down on the water to be used in the mix, raise its strength, and save the amount of cement used. it improves the mechanical and physical performances of the hardening cement, with no harmful corrosive effect on steel reinforcements.

Application
ZT-2Set-retarding, water-reducing agent is applicable to mass concrete, slip-form construction in summer, and concrete work or reinforced concrete word ghat requires slow –setting of cement; it is also suitable for cast-in-situ or prefabrication of concrete or reinforced concrete members, when no constructin joints are desired for mass concrete in hot summer.
 

Other Information
ZT-2Set-retarding, water-reducing agent is A GRAYISH YELLOW ADDITIVE. The amount to be added in concrete ranges between 0.5% and 1.5% as the project demands. It can be put into the mixer together with the cement. The agent must be kept in a dry place; in case coagulums have been formed, it should be broken into powder before put to use, Validity for use is 2 years.
