PUMPABLE AGENT
APPLICATION
Itcan be utilized in premixed &pumpable concrete,commercial ready-mixed concrete,bulky concrete,armored boncrete and auto-flowable and self-sealing concrete ete.
PROPERTIES.FEATURES&CHARACTERISTICS
1,Appearance:Light brown powder or dark brown aqueous solution .Anti-freezer can be added when construction is launched below zero cegree C.
2,Stable chemical performan ces are refleeted by its properties of being non-poisonous,odorless and non-inflammable.No crystallization occurs in winter.
3,Water reduction exceeds 22%as a condition of blending where C80 r lower grade concrete is prepared.
4,Freedom from chloride interference makes it possible that little shrinkage occurs.
5,Good retardation will be enerated to reduce premature hydration heat.Initial setting duration can be extended to 10 hours.Alternatively make adjustments according to customers´requirements.Zero water penetration and segregation,and good moisture insulation are obvious characteristics.Gas cannot be exhausted in 2 hours so that its anti-bending ability,modulus of elasticity,water proof and anti-infiltration will be correspondingly improved.
6,Compatible with varieties of cement.Preferably blended with superfine mineral blending materials.

The above blend dossage is recommended for reference.Proper adjustments should be made accordingly.Keep direct contact with manufacturer when C50 or concrete of higher index is readily prepared.
DJRECTIONS
1The powdery agent can be applied to concrete directly or prepared accordingly and diluted to different concentration levels.The liquid agent can be blended straight with concrete.
2 In case of combination with expansion agent an extra 30-second agitation is required.
