Product Description
zt-1 is non-air-entraining type superplasticizer, the chemical name is ² -naphthalene sulfonate formaldehyde condensate.

Product Feature
1. Appearance: Light brown powder; dark brown liquid. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
2. Remarkable Plasticity.when the agent is admixed at 0.5^ 1.5 , water reduction rete up to 12-28% , early strength and strength effect extremely show .Statistically, compression strength on the 3rd day, the 7th day and the 28th day is increased by 60- 130 , 40-60% and 20-40% respectively.
3. 15-20 of cement can be reserved when the agent is blended, which is preconditioned by same collapsibility and strength.
4. Improve miscibility of concrete amalgamator with water and collapsibility as well, As the result, compression strength, tensile strength, buckling strength and modulus of elasticity will be improved to some extent.
