Water reducing admixtures are concrete additives that help reduce the water needed for a mix while maintaining the required fluidity. PC-733 is a powder polycarboxylic acid superplasticizer made through modified polyether polymerization and spray drying. Its stated water reduction is at least 25%, and its recommended dosage is 0.10% to 0.40% of the cementitious material.

Reducing water consumption can help produce a denser hardened slurry and support concrete strength. PC-733 also supports fluidity across cement, admixture, and other material systems.

PC-733 is suitable for Portland cement concrete systems, including ordinary concrete, high-performance concrete, mass concrete, and special concrete. It can also be used in concrete containing large amounts of fly ash or ore powder.

A buyer planning a high-performance or mass concrete mix can consider PC-733 when the formulation needs water reduction and workable flow. The final dosage should follow the concrete design and the actual raw materials in the mix.

PC-733 can be measured and mixed with water before it is added to the concrete. It can also be added with water after the concrete has been introduced, which is the preferred method in the product instructions. Another option is to add the required water to the powder until the needed solid content is reached, then add the liquid according to the concrete mix amount.

For dry-powder premixing, mix the powder evenly before adding water. This matters in a working batch where uneven distribution could affect the consistency of the concrete. A concrete producer should set the dosage within the 0.10% to 0.40% range according to the mix design and raw materials.

PC-733 is supplied as a white powder. Its key technical values include an effective content of at least 95%, water content of no more than 5.0%, bulk density of 500 to 700 g/L, and a pH value of 6 to 8 for a 10% aqueous solution at 20°C. Chloride ion content is no more than 0.1%, air content is no more than 6.0%, and base content is no more than 3.0%.

These values give procurement and quality teams a starting point for reviewing the product against their concrete formulation and incoming-material checks.

PC-733 is packed in paper-plastic composite bags at 25 kg per bag. Store the bags in a ventilated, dry place, protect them from moisture and direct sunlight, and seal opened material promptly to prevent moisture absorption and deterioration.

The storage period is 12 months from the production date. If the material is beyond that period, it must be tested before use. For an order review, send the planned dosage, cementitious-material quantity, concrete type, and expected bag quantity to the supplier.
