ZY-800 is compounded of polycarboxylate superplasticizer and micro-expansion & shrinkage resistance materials, and achieves the dispersion of cement by the steric effects provided by electrostatic potential sets of side chain. By adding high performance dispersant and functional components, ZY-800 is designed to ensure the possibility for the concrete to satisfy the needs of different building construction.
 

With the excellent water reducing rate and multifunctionality, ZY-800 works well in both keeping rheological properties before the hardening of cement and shrinkage resistance property after hardening. In addition, ZY-800 can meet the requirements of environmental protection in the future.
 

ZY-800 is fully compatible with those major chemical additives used for the production of concrete additives, but data show that ZY-800 is incompatible with Naphthalene sulfonate water reducer.
 

Typical analysis:
Main ingredient: Polycarboxylic ethers (water soluble)

Dosage: recommendation of additive volume is 2.5%～5.5%. And the optimum dosage could be adjusted according to the design performance of concrete mixture. With a broad range of doses, ZY-800 makes concrete hold effective controlling capacity on slump constant time by adjusting doses.
 

Storage:
Prevent the erosion caused by climate. The storage temperature should be between 5°C ~ 40°C.
Under these conditions, the product should be used within three months after the delivery.
 

ZY-800 is non-dangerous goods, but inedible. Avoid contact with skin and eyes when using. If swallowed by mistake, immediately sent to hospital for treatment. If spilled, absorb the spills with the sand, soil or other inert materials, carry them away by suitable containers, and flush out the residue with plenty of water. The disused and expired product should be disposed in accordance with the local Waste Disposal Ordinance.
