Product Description:

Our Low Temperature / Temperature Controlled Concrete is specially designed to manage the heat generated during cement hydration, particularly crucial for mass concrete pours in Malaysia's warm climate. By utilizing specific materials, admixtures, or cooling techniques, this mix minimizes peak concrete temperatures, reducing the risk of thermal cracking and ensuring long-term durability. Compliant with MS EN 206 and project specifications for temperature control.

Key Features:

• Mix Type: Ready-Mixed Concrete with Controlled Heat of Hydration / Placement Temperature.
• Mechanism: May use cements with low heat of hydration (e.g., blended cements with PFA/GGBS), chilled mixing water, ice flakes, liquid nitrogen cooling, or specific admixtures (retarders) to control temperature rise and/or lower initial temperature.
• Properties: Lower peak temperature during hydration, reduced thermal gradients, minimized risk of thermal cracking, potentially extended workability. Maintains specified strength (specify grade).
• Compliance: Meets MS EN 206 and specific project requirements for maximum temperature or temperature differentials.
• Application Focus: Primarily for mass concrete structures.

Ideal for:

• Mass concrete foundations, raft slabs, dams.
• Thick structural elements where heat build-up is a concern.
• Large volume pours conducted in hot weather conditions.
• Projects with strict limits on concrete temperature to prevent thermal cracking.

Benefits:

• Prevents Thermal Cracking: Reduces temperature differences within the concrete mass, minimizing cracking risk.
• Improved Durability: Enhances the long-term integrity of mass concrete structures.
• Ensures Compliance: Meets project specifications related to temperature control in concrete.
• Manages Hot Weather Placement: Helps control setting times and maintain workability in high ambient temperatures.

Important Notes:

• Requires careful planning regarding mix design, delivery logistics (potentially cooled trucks), placement sequence, and curing methods (insulation may be needed).
• Temperature monitoring on-site is often required.
• Mix design and cooling method depend on the project requirements and scale.
• Delivery via concrete mixer truck. May involve specialized logistics.
