Specialized for Concrete Pouring in Cold and Freezing Weather

What is Anti-Freeze Concrete Gel?

Anti-Freeze Concrete Gel is an additive designed using silica fume, polycarboxylate ether, water repellent materials, fillers, polypropylene fibers, and setting accelerators. It is uniquely formulated for concrete pouring in regions with cold and freezing weather conditions down to -8°C.

This gel can be used for creating high-strength, impermeable, and durable concrete. It also helps in improving the density of concrete and increasing its compressive, bending, and tensile strengths. Additionally, this additive enables a reduction in the cement content by 15 to 20 percent.

In general, this product is used during concrete pouring in cold weather conditions. It works by lowering the freezing point of the water within the concrete, increasing the internal temperature, which allows for concrete pouring in winter and helps prevent damage to concrete structures in cold regions.

How Does Anti-Freeze Concrete Gel Work?

The silica fume in the gel formulation is a powerful pozzolanic material that can replace cement, yielding results similar to that of cement. When mixed with water and calcium hydroxide, it reacts to form calcium silicate hydrate, which significantly contributes to the hardening of concrete and increases its strength. Additionally, the polycarboxylate ether in the formulation acts as a superplasticizer, forming a coating on cement particles that prevents their aggregation, and generates a repulsive force due to like charges, which helps in keeping the concrete workable.

The polypropylene fibers in the gel improve the mechanical and abrasion resistance of the concrete. The setting accelerators in the formulation speed up the hydration process and prevent freezing of the concrete before it sets.

Properties and Effects of Anti-Freeze Concrete Gel

• Prevents corrosion of reinforcement bars and steel plates
• Prevents freezing of water in the concrete before the hydration process
• Improves rheological properties of the concrete in the plastic state
• Reduces cement content by 15 to 20 percent
• Prevents cracks caused by thermal stresses in the concrete
• Prevents water bleed and segregation of the concrete
• Increases compressive, tensile, and bending strength
• Increases abrasion and electrical resistance of concrete
• Reduces water-to-cement ratio by up to 20 percent
• Improves concrete durability and stability in freeze-thaw cycles
• Significantly reduces surface cracks in concrete
• Reduces permeability to water, chloride ions, and sulfate attack
• Provides an attractive exposed surface finish
• Facilitates easy pumping and reduces wear on concrete pouring equipment
• Produces homogeneous and workable concrete

Usage Amount of Anti-Freeze Concrete Gel

The optimal dosage of Anti-Freeze Concrete Gel is typically between 5 to 8 percent of the cement weight. To achieve high compressive strength and a robust concrete mix, 10 to 15 percent of the water in the mix should be reduced before adding the gel. The quantity added is dependent on the ambient temperature and the desired setting time.

How to Use Anti-Freeze Concrete Gel

The gel can be added to the concrete in two ways:

1. Mix the product with part of the mixing water and then add it to the dry mix.
2. Add the gel after all the components of the concrete mix have been combined.
