Polikcarbopylate Superticizer

PCA-40 polycarboxlate-based (40% liquid)

Product Description
PCA-40 is a polycarboxlate¬ -based high¬ Range water ¬ Reducing admixture specifically third generation technology to meet the needs of the concrete industry. PCA-40 is manufactured under closely controlled conditions to provide uniform, predictable performance and is formulated to comply with specifications for Chemical Admixtures for Concrete. PCA-40 does not contain intentionally added calcium chloride.

Uses
PCA-40 superplasticizer produces concrete with extremely workable characteristics referred to as high slump. It also allows concrete to be produced with very low water/cement ratios for high strength. PCA-40 is also used in scope of the ready-¬ Mix concrete, precast concrete and self¬ Consolidating concrete. The special formulation of TPCA-41 helps maintain the plasticity of the concrete and extends its workability time during warmer months when slump loss and fast stiffening of the fresh concrete can be a concern.

Product Advantages
1. TPCA-40 can be dosed in small amounts to obtain water reduction from 10-15%, and will achieve water reduction up to 45% at high dosage rates.
2. Provides a combination of slump life with near neutral set time
3. Consistent air entrainment
4. Highly efficient, producing high slump concrete at very low dosages
5. Concrete finishes easily without stickiness, spotty set or tearing
6. WhilePCA-40 is ideal for use in any concrete where it is desired to minimize the water/cementitious ratio yet maintain worka¬ Bility.
7. High early compressive strengths for earlier removal of forms and structural use of concrete.

Addition Rates
PCA-40 superplasticizer addition rates can vary with type of application, but will normally range from 0.3% to 0.6% (0.3-0.6/100 kg) of cementitious. In mostinstances, the addition of 0.4-0.5% ( 0.4-0.5/100 kg) ofcementi¬ Tious will be sufficient. At a given water/cementitious ratio, the slump required for placement can be control LED by varying the addition rate. Should conditions require using more than the recommended addition rates, please consult our company engineer.
PCA-40 dosage requirements may alsobe affected by mixdesign, cementitious content and aggregate gradations.

Compatibility with Other Admixtures
PCA-40 is compatible with most admixtures aslong as theyare added sepa¬ Rately to the concrete mix. However, PCA-40 is not recommended for use in concrete containing naphthalene-¬ Based admixtures. Ingeneral, it is recommended that PCA-40 be added to the concrete mix near the end of the batch sequence for optimum performance. Different sequencing may be used if local testing shows better performance.

Other
Pretesting of the concrete mix should be performed before use and as conditions and materials change in order to assure compati¬ Bility with other admixtures, and to optimize dosagerates, addition times in the batch sequencing and concrete performance. For concrete that requires airentrainment, the use of an air¬ Entraining agent is recommended to provide suitable air void parameters for freeze¬ Thaw resistance. Please consult our company presentative for guidance.
