zt-1 is non-air-entraining type superplasticizer, the chemical name is β-naphthalene sulfonate formaldehyde condensate.
APPLICATION
1ãWidely used in pre-cast & 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.
2ãSuitable for preparation of flowing concrete, early-strength concrete, high-strength concrete, Precast vapor-cured concrete, prestressed concrete and its formulations.
3ãCompatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc.
4ãUsed as master batch for preparation of admixtures of different characteristics (such as early strength and water-reducing agent, retarding and water-reducing agent, pumped anti-freezing agent and pumped water-reducing agent, etc.),to fully meet the requirements of different types of construction, construction technology, and temperature terms.
PROPERTIES, FEATURES & CHARACTERISTICS
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 0.5ï¼ , 40-60% and 20-40% respectively.
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.

Instructions 1. powder: as the cementitious materials;liquid: as the solid content. 2. post-doping is better, appropriate extension of mixing time in order to facilitate uniform. 3. the liquid should be above 15 â used and stored, to avoid crystallization. RACKGING, TRANSPORTATION AND STORAGE |
