Plastiment PR 250 PK | MCT CHEMICALS | SIKA PAKISTAN PRIVATE LIMITED

Usage:

Plastiment PR 250 PK is used in various concrete and mortar applications, including:

• Ready-Mix Concrete: Used in concrete batching plants to enhance the workability and performance of ready-mix concrete.
• Precast Concrete: Ideal for improving the quality and consistency of precast elements, especially in terms of finish and surface texture.
• High-Strength Concrete: Helps reduce the water-cement ratio, resulting in high-strength concrete with better compressive strength.
• Flooring and Paving: Improves the workability of concrete used in flooring, industrial paving, and other decorative applications.
• Mortar & Plaster: Used in the production of high-performance mortar and plaster to improve flow and bonding properties.
• Concrete Repair: Enhances the bonding and workability of repair mortars and concrete repair mixes, ensuring a stronger and more durable repair.

Application:

1. Mixing: Plastiment PR 250 PK should be added to the mix during the batching process, either along with the water or separately, depending on the specific batching procedure. The recommended dosage is typically 0.2% to 0.6% by weight of cement, but this can vary depending on the specific application and desired results.
2. Concrete Consistency: The admixture helps improve the flow and consistency of the concrete mix without adding extra water, making it easier to handle, place, and compact.
3. Workability: Plastiment PR 250 PK is particularly effective in hot weather or dry conditions, where it helps maintain workability even in challenging environments.
4. Compatibility: Plastiment PR 250 PK is compatible with most other concrete admixtures, including retarders and accelerators, but it’s essential to ensure compatibility before use in combination with other additives.
5. Curing: As with all concrete mixes, proper curing is essential. After application, allow the concrete to cure for the recommended time (typically 24 to 48 hours) to ensure maximum strength and durability.

Coverage Advantage:

Plastiment PR 250 PK is a highly efficient plasticizer that provides excellent coverage with a small dosage. A typical dose of 0.2% to 0.6% by weight of cement significantly improves workability while maintaining the concrete’s strength and durability. This efficiency makes it a cost-effective solution, as a little amount of the product goes a long way in improving concrete performance. The reduced water content also helps minimize shrinkage and cracking, leading to longer-lasting concrete.
