An acrylate polymer, commonly referred to as acrylic or polyacrylate, belongs to a family of polymers derived from acrylate monomers. These plastics stand out for their clarity, durability against breaking, and flexibility.
Acrylic polymer contributes to concrete’s aesthetics, longevity, and bond strength. The main aim of using the polymer in concrete is to maintain internal moisture and reduce porosity, which minimizes bacterial growth and oxygen exposure, ultimately preventing deterioration. Acrylic can also be used as a filler in cracks and voids in concrete.
What is Concrete?
Concrete is a composite material made of powder or fine grains suspended in binder solutions. When portland cement is used as the binding agent, concrete or cement mortar is the material produced. Concrete should be a heterogeneous solution with varying properties depending on the processing or composition method.
The concrete commonly comprises approximately 15% water. The water should be pure without any additives. The quality of the concrete lies mainly in the cement and aggregates used. Cement is commonly combined with additives like sodium sulfate or carbonate to adjust the temperature resistance and pH of the final product.
Adding a polymer can help reduce salt, carbon dioxide, and chloride intrusion and permeability. The best thing is that the polymers increase abrasion resistance and are suitable for cross-linking. Of all the polymers available, acrylic has the best breathability (water vapor transmission rate).
The Role of Acrylic Polymer in GFRC
Glass Fiber Reinforced Concrete (GFRC) is used in countertops, architectural panels, fountains, and planters. Acrylic polymer is introduced to the production of GFRC before casting. When the powder is subjected to 80 degrees Celsius temperatures, it melts and flows to open areas in the mix.
Letting the mixture cure overnight or during the first day under plastic is advisable. This helps the polymer come together and form an internal curing membrane while the concrete is kept moist. Acrylic polymer’s moisture retention properties are essential for long-term curing and improving the concrete’s strength.
Some of the benefits of acrylic polymers include:
- Improved workability
- Facilitates pigment suspension
- Enhances the strength of the concrete after it is hardened
- Enhanced ductility
- Offers freeze-thaw resistance
- Reduces shrinkage cracks after casting
