Charanteristics

1 Main technical properties of the product such as poly-merization degree, surface tons on ,net cement paste fluidity, water reduction rate and improvement of work ility of concrete, etc. Can will be compared with the current products of the same type on the interna-tional market.

2 Addition of 0.5~1.0% SNF type waten-reaneing agent (powdered) into concrete by weight of cement can reduce 15~25% of mixing water with very little entradned air, thus increasing the compressive strength of the concrete by 25~75% for 3 days and by 15~40% for 28 days , Its tensils strength, bending strength, modulus of elasticity and reinforcement bond can correspond dingly be raised as well. The product contains no chloride, therefore no corrosion effect will be exercised on steel reinforcement. The product has no apparent influence on the setting time of the concrete, and excess of additives will not incur any retardation either.

Scope of Application:

1 Fit for preparation of early strength concrete, high strength concrete, high-impermeability concrete, self-compaction concrete and for preparation of the concrete with its class corresponding to that of the cement used.

2 Can be widely applicable to naturally cured concrete and steam cured concrete, reinforced concrete and prestress-ed reinforced concrete.

3 Fit for preparation of self-flowing grouting materials.

4 Can also be taken as a teahnical measure to economize cement in concrete construction.

Method of application:

Water should first be added to either liquid or powdered products, so as to obtain required consistency, and then admix them into the concrete with exact dosage.

Amount of Admixture:

Appropriate dosage of admixture is 0.5~1.0% (powdered) by weight of cement.

Cases of Application:

SNF Type water-Reducing Agent has been

1 Used for high fluidized, self-compaction pump concrete for pump house at the power station in Bao shan steel mill.

2 Used for self-flowing grouting materials for the project of 200m span highway bridge at maogang, shanghai.

3 Used for oil-impermeable concrete for floors of multi-story industrial building's in shanghai car Repair plant.

4 Used for high strength concrete bridge components in a Bridge components plant in Fengxian county.

5 Used for precas ? concrete elements naturally cured and steam cured in precast concrete products Factory. After application in scores of projects, the resuit is satisfactory.
