PCE Polycaboxylate Superplasticizer Concrete Additives for Water Reducing:

DESCRIPTION:
PCA(I) concrete superplasticizer is a polycarboxylate polymer-based composite admixture. It is a liquid  which has the performances of high range water reduction, excellent slump retention and strengthening.  It is specially adapted to the production of high durability concrete, self-compacting concrete,  high compressive strength concrete, and high workability concrete. PCA (I) superplasticizer is formulated  to comply with the following specification for concrete admixture: ASTM494, Type G; GB8076-1997.  The relative densities of PCA(I) whose solid content are 21.7% and 50% are approximately  1.06 and 1.17 respectively.

TECHNICAL PROPERTIES:

FEATURES:

High range water reduction
The water reduction rate can be up to 35% at high dosage rates.

High compressive strengths
It can improve the compressive strengths of concrete by 60-100% at the age of 3 days, 60-90%  at the age of 28 days and 30-50% at the age of 90 days.

High slump-retention
Almost no slump loss of the concrete within 2 hours.

Excellent workability
No bleeding or segregation, no bleeding mark or obvious bubble defect on appearance.

High durability
It effectively improves the frost resistance and carbonation resistance of the concrete. It can decreases drying

shrinkage of the concrete by 20% or more compared to naphthalene-based admixture.

High compatibility
Compatible with a far greater range of cement types and mineral additives. It particularly fits for the preparation

of high durability concrete and self-compacting concrete with fly ash and grinding slag.

High stability
No delamination and sedimentation during its shelf life and no crystallization in winter.

DOSAGE&USAGE
The addition rate of PCA(I) normally is 0.6~1.2% by weight of cementitious materials, and can be increased to

1.3-1.8% for ultra-high strength and durability concrete.

Don’t mixed with naphthalene-based admixture. If other admixtures, such as retarded or corrosion-inhibiting admixture,  are required simultaneously for some special projects, compatibility tests should be conducted beforehand.
Curing:The concrete should be wet-cured and covered after final setting, and surface-cured in winter to prevent rost attack.

PACKAGING
PCA(I) is in the state of liquid and should be stored and transported in plastic barrel. IBC Tank
