⭐ Fosroc Conplast RP264 – High-Performance Retarding Plasticiser for Professional Concrete Applications

Fosroc Conplast RP264 is a high-quality, specially formulated retarding plasticiser admixture designed to provide exceptional control over concrete setting time while significantly improving workability. In modern construction, where durability, precision, and operational efficiency are crucial, Conplast RP264 delivers superior performance—especially in hot climates, long transportation routes, and large or continuous concrete pours.

This advanced admixture is fully chloride-free, making it completely safe for reinforced concrete structures. Its unique formulation uniformly slows the hydration process without compromising the final strength, density, or durability of the concrete. At the same time, its plasticising action enhances flowability, compaction, and surface finish, establishing it as a trusted solution in ready-mix and on-site concrete systems.

✔️ Product Overview

Conplast RP264 is a liquid retarding plasticiser that disperses cement particles effectively, ensuring an extended workable period and improved mixing properties. It prevents premature stiffening of concrete, which is a common challenge in hot weather or during long transit times.

Through controlled retardation and enhanced plasticisation, the admixture ensures consistent, high-quality concrete suitable for complex structural works. It is widely used in:

Large rafts and foundations

RCC structural elements

Mass concrete works

Long-distance concrete transportation

Ready-mix batching plants

Pumped concrete systems

Its robust chemical design stabilizes concrete even under temperature variations, maintaining uniformity and reliable performance in every batch.

✔️ Key Functional Benefits

1. Controlled and Predictable Setting Time

One of the most valuable features of Conplast RP264 is its ability to delay the initial setting time of concrete. This advancement ensures a longer operational window, allowing contractors to work comfortably without the risk of rapid stiffening—especially in warm climates.

Prevents flash-setting

Enables extended workability

Reduces the formation of cold joints in continuous pours

2. Enhanced Workability Without Extra Water

Even without increasing the water content, the admixture significantly improves the workability and fluidity of concrete.

Easier placement & finishing

Improved compaction

Reduced segregation and bleeding

Smooth, professional surface finish

3. Superior Pumpability

Conplast RP264 enhances the lubrication and cohesiveness of the mix, making it ideal for pumped concrete.

Reduces friction in pipelines

Enables long-distance and high-rise pumping

Ensures consistent flow

4. Chloride-Free & Safe for Reinforcement

Its non-corrosive formulation protects reinforcement bars from rust and provides long-term durability.

Safe for RCC and prestressed concrete

Maintains structural integrity

5. Increased Operational Efficiency

Better workability and extended setting time reduce manpower pressure and enhance onsite productivity.

Less waste

Reduced load rejections

Smoother construction flow

✔️ How Conplast RP264 Works

The admixture modifies cement hydration by dispersing cement particles electrochemically. This:

Maintains a fluid, workable consistency

Slows early hydration to control setting time

Enhances uniformity in the concrete matrix

Reduces temperature rise during the early curing phase

This scientific approach results in a stable, predictable concrete mix suitable for demanding construction conditions.

—

✔️ On-Site Advantages
