Product Description
PCA(IV) is a new generation superplasticizer based on modified Polycarboxylic ether. It provides maximal water reduction, increased early strength, and improved finishing characteristics. PCA(IV) does not contain formaldehyde, calcium chloride or any other intentionally added chlorides and will not initiate or promote the corrosion of steel present in the concrete. It is formulated to comply with the following specification for concrete admixture: ASTM494, Type F; BS EN934: 2/3.2.3.
| Features and Benefits: |
| 1. High range water reduction: PCA ® (IV) can be dosed in small amounts to obtain water reduction from 15 to 30, and will achieve water reduction up to 45% at high dosage rates. 2. High Plasticity: The superplasticizing action of PCA ® (IV)provides high-slump, flowing concrete that maintains excellent workability and may be placed with minimal vibration even at very low water cement ratio's as low as 0.25. 3. High compressive strengths: Increases the compressive strengths of concrete by 50-120% at the age of 3 days, 80% at the age of 28 days and 30-50% at the age of 90 days. 4. High durability: Effectively improves the frost resistance and carbonation resistance of the concrete. Lower drying shrinkage of the concrete by 20% or more compared to naphthalene-based admixture. 5. High compatibility: Compatible with a far greater range of cement types and mineral admixtures. Particularly fit for the preparation of high durability concrete and self-compacting concrete with fly ash and ground slag. 6. Good concrete appearance: Improves surface appearance of concrete obviously. 7. Dosage: The addition rate of PCA ® (IV) is normally 0.5~0.7% by weight of cementitious materials, and can be increased up to 0.9% if more water reduction or slump retention is required. |
| Mixing PCA ® (IV) is a liquid admixture to be added to the concrete during the mixing process. Optimum plasticizing effect and thus water reduction is achieved if PCA ® (IV) is added immediately after 50 -80% of the water. Avoid adding PCA ® (IV) to dry aggregate or cement. Compatibility PCA ® (IV) can be used in combination with the following admixtures and additives 1. Air entraining admixtures to optimize freeze/thaw durability 2. Silica Fume for higher density 3. Shrinkage compensating admixtures 4. Synthetic and Steel Fibres 5. Concrete Improvers PCA ® (IV) is not compatible with the traditional hyperplasticisers with a naphthalene sulphonate or melamine sulphonate base condensed with formaldehyde. |
