Project Description
Cement Defoamer & Concrete Admixture Antifoams
Effective foam control using specialized defoamers for construction materials is essential for ensuring the workability, strength, and durability of modern building projects. Uncontrolled air entrainment in cement slurries, mortars, grouts, and concrete admixtures leads to significant structural cavities and application failures.
INVINO® provides a range of solutions specifically engineered to tackle unique foam challenges in the demanding conditions and complex chemistries involved in cementitious systems. During the mixing of dry-mix mortars or the synthesis of Polycarboxylic Acid (PCE) water reducers, excessive macro-foam generation compromises the final compression limits and surface aesthetics of the hardened concrete matrix.
Our specialized formulation active defoamers regulate spatial air-void structures without causing oil-bleaching or layer separation boundaries. This securely anchors the air content within standard parameters, ensuring reliable flow metrics and dense surface finishes under harsh high-alkali hydration thresholds.

Key Application Areas for Construction Defoamers
Controlling foam in cementitious formulations is crucial for achieving strict targets for air content, structural density, and long-term workability metrics across functional grouts and heavy masonry blocks.
Polycarboxylic acid (PCE) superplasticizers are highly prone to air entrainment. Our specialized liquids provide continuous compatibility and long-term foam suppression inside high-concentration aggregate admixtures.
In dry-mix compounds, foam compromises core compressive strength parameters and layer aesthetics. Free-flowing solid powder additives ensure instantaneous air release upon hydration, securing smooth mirror-like surface leveling.
Regulating gas bubbles within high-solids cement slurries is critical during fiber cement board sheet preparation. Active polymer agents prevent micro-void defects, securing structural load uniformity on final products.

Frequently Asked Questions (FAQ)
Q: Is this defoamer compatible with Polycarboxylate Ether (PCE) Superplasticizers?
A: Yes. INVINO-8061 / 8081 are specialized polyether polymers synthesized for high solubility stability parameters inside highly concentrated aqueous PCE liquids. It prevents phase separation or oil-slicking drifts during extended storage cycles.
Q: Will using this defoamer improve the compressive strength of concrete?
A: Yes. By eliminating structural macro-bubbles and dynamic air pockets entrained during aggressive mechanical mixing, the active compounds optimize core consolidation density metrics, successfully maintaining hardened compressive strengths.
Q: Can it help eliminate "bug holes" on the concrete surface?
A: Yes. Volumetric accumulation of macro-bubbles at the mold interface boundary yields surface cratering and "bug holes". Our anti-foaming chemistries provide continuous rapid bubble drainage to secure smooth precast drawdown aesthetics.
Q: Is the defoamer stable in high-alkaline environments (High pH)?
A: Yes. Hydrating cement matrices typically exhibit severe alkaline environments with pH baselines up to 12.0–13.0 boundaries. INVINO® dry powder agents utilize robust inorganic support carriers to prevent chemical hydrolysis degradation under high pH parameters.
Q: How should I apply the defoamer? Direct addition or pre-mix?
A: For dry-mix aggregates (mortars, plasters), the powder grade must be pre-blended uniformly along with dry feedstocks. For liquid concrete admixtures, direct metering addition during the formulation let-down cycle under mechanical agitation ensures homogeneous active matter dispersion.
