Defoamers for Cement, Mortar & Concrete
Effective foam control is critical in cementitious systems like ready-mix concrete, pre-cast elements, mortars, and grouts. Uncontrolled air entrainment can severely compromise final compressive strength, density, and surface appearance.
INVINO provides a range of high-performance concrete defoamers and cement antifoams engineered to optimize air content, improve workability, and ensure the structural integrity of the final product.
Critical Challenges in Cement & Concrete Admixture Formulation
Polycarboxylate ether (PCE) superplasticizers inherently entrain large amounts of irregular air voids. Selecting the correct defoamer for your cementitious systems and concrete admixtures is essential for long-term stability and structural integrity.
PCE Compatibility & Storage Stability
Many defoamers separate or cause oil slicks when stored in admixture tanks. Our modified polyether and silicone formulations are designed for long-term phase stability within the PCE mother liquor, ensuring uniform dosing.
Compressive Strength Optimization
Excessive entrapped air (macro-bubbles >1mm) significantly reduces compressive strength. Our agents rapidly break macro-bubbles while retaining the necessary micro-air void system for freeze-thaw durability.
Surface Aesthetics (Bug Holes)
Air bubbles trapped against the formwork result in honeycombing and bug holes. Highly efficient degassing agents improve workability, yielding a dense, smooth, and aesthetically pleasing concrete surface.
