CIBEX300

Powder Additive for Shrinkage Compensation

Suitable for Cement-Based Mortars and Grouts

Description of the Expanding Agent for Mortar and Grout

What is CIBEX (Expanded) – the Expanding Agent for Grout and Mortar?

CIBEX is a powdered additive designed to counteract shrinkage and cracking in fresh or hardened concrete. Shrinkage, usually due to hydration, loss of water, or absorption by surrounding materials, often leads to cracks in concrete sections. This issue, along with other factors like cement type, water content, curing procedures, and environmental conditions, can severely affect concrete quality. Therefore, an agent like CIBEX is needed to compensate for these shrinkage effects. Formulated from expanding agents and nano-silica, CIBEX is added to grout or mortar to control shrinkage and prevent cracking. The use of this additive improves compressive strength and is crucial for projects involving cement-based grouts and mortars, such as repairs, and it enhances the durability of the final product.

This product is also recognized as a high-performance grout with excellent resistance, making it ideal for industrial and construction applications that demand long-term stability.

Mechanism of Action for the Expanding Agent

CIBEX works by introducing controlled expansion into the grout or mortar mixture, compensating for shrinkage that occurs due to evaporation. The expanding effect is precisely controlled to prevent cracking, thus improving the cohesion of the mixture. By adding this product to the concrete matrix, the detrimental effects of shrinkage and the associated risks of cracks are mitigated.

Properties and Effects of CIBEX Expanding Agent for Grout and Mortar

• Shrinkage Compensation: Effectively compensates for plastic shrinkage, preventing cracks in freshly mixed mortar or grout.
• Compatibility: Works with all types of Portland cement except Type 5 cement.
• Easy to Use: Can be added directly to the mix during construction, making it convenient for on-site use.
• Enhanced Bonding: Improves bonding between steel and surrounding materials.
• Controlled Expansion: Provides controlled expansion to the grout or mortar.
• Increased Compressive Strength: Enhances the compressive strength of concrete and mortar.
• Prevention of Cracking: Prevents cracks due to shrinkage.
• Water Retention: Reduces water bleed in the mortar or grout.
• Quick Strength Development: Achieves early compressive strength.

Applications of CIBEX Expanding Agent for Grout and Mortar

• Filling Gaps and Joints: Suitable for filling spaces between structures.
• Concrete Pouring in Tight Spaces: Ideal for confined areas.
• Underpinning Steel-Framed Buildings: Used in base preparation for steel-frame structures.
• Industrial Machinery Base Plates: Perfect for grouting beneath machine bases in industrial settings.
• Rebar Installation: Used in mortar for rebar stabilization.
• Railway and Crane Rails: Effective for filling gaps around rails in industrial plants.
• Injection Grouting in Dams and Tunnels: Applied in large-scale construction projects.
• Repair Mortars: Used in repair applications to prevent shrinkage.
• Non-Shrink Grout: Suitable for producing non-shrink grouts.

Consumption Rate

The consumption rate of CIBEX depends on factors such as the type of aggregate, cement, environmental conditions, and the specific mix design. However, a typical usage rate is 0.5% of the cement weight.

Application Method

For best results, add CIBEX to the mix after combining all other components and water. It should be mixed for at least 1 minute per cubic meter to ensure uniform distribution. The expansion should occur naturally without applying external pressure, allowing the grout or mortar to fill gaps. It is recommended to use a superplasticizer along with CIBEX for better distribution and to reduce the water content, which improves the overall strength.

Safety Instructions

• Personal Protective Equipment (PPE): Wear gloves and safety glasses during application.
• Inhalation Risk: Avoid breathing dust during mixing.
• Ingestion: If ingested, seek immediate medical attention.
• Skin Contact: Avoid prolonged direct contact with the skin.

Storage

CIBEX should be stored in a dry place, away from extreme temperatures, frost, and prolonged sunlight. The recommended storage temperature is between 10°C and 30°C.

Shelf Life: 1 year in the original packaging.
