Overview of Defoaming Agent

Concreteandmore’s concrete defoaming agent is a high-efficiency chemical additive specially developed for cement-based systems, designed to eliminate excessive and unstable air bubbles generated during concrete mixing, pouring and transportation. These harmful bubbles can reduce the compressive strength of hardened concrete, cause honeycomb-pockmarked surfaces, and shorten the service life of buildings. Our defoaming agent quickly destabilizes bubble films, breaks existing bubbles and inhibits new ones, making concrete denser, more uniform, and improving both mechanical performance and surface quality for various construction scenarios worldwide.

Features of Defoaming Agent

• Rapid Defoaming & Long-lasting Foam Suppression: It can complete defoaming within 30-90 seconds after mixing with water, effectively eliminating existing bubbles and inhibiting new foam formation during the entire construction process.
• Excellent Compatibility: Well-matched with polycarboxylate (PCE) ngaahi meʻa fakapalasitiki lahi, naphthalene-based water reducers and other common concrete admixtures, no demulsification, oil floating or adverse reactions.
• High Adaptability: Stable performance in a wide temperature range (from -5°C to 40°C) and strong acid-alkali environment (pH up to 14), suitable for various construction conditions and regions.
• Fakamole-Ola Lelei & Low Dosage: Taha pe 0.01% ki 0.3% dosage by weight of cement is needed to achieve optimal defoaming effect, reducing construction costs significantly without affecting concrete performance.
• Fakakaume'a mo e 'atakai & Malu: 'Ikai kona, taʻe nanamu, free of harmful substances and chlorides, complying with international environmental and construction safety standards, no pollution to the environment or corrosion to steel bars.

Applications of Defoaming Agent

Concreteandmore’s concrete defoaming agent is widely used in various cement-based materials and construction projects, suitable for scenarios requiring high surface quality and mechanical strength:

• Sima mateuteu-Mix: Eliminates bubbles in commercial concrete mixing, ensuring uniform texture and improving pumpability during transportation and pouring.
• Sima Precast: Perfect for precast components (ngaahi pou, ngaahi kōlomu, ngaahi laupapa, mo e ngaahi me'a pehē.), reducing surface defects and ensuring consistent quality of finished products.
• Grouting Materials & Self-Leveling Mortar: Ideal for grouting projects and self-leveling floors, avoiding surface pores and ensuring flatness and compactness.
• Building Mortar: Used in waterproof mortar, bonded mortar, wall putty and gypsum products, preventing foam-induced cracks and improving adhesion.
• Ngaahi Poloseki Langa Lalahi: Applicable to high-rise buildings, ngaahi hala, ngaahi halafakakavakava, ngaahi vaitupu, ports and other projects, enhancing concrete durability and service life.

FAQs of Defoaming Agent

1. What is the function of concrete defoaming agent?

It removes excessive air bubbles from fresh concrete, improves concrete density, compressive strength and surface smoothness, and avoids structural defects caused by bubbles.

2.Is your defoaming agent compatible with PCE superplasticizers?

ʻIo, our defoaming agents are specially designed to be compatible with PCE superplasticizers, SNF superplasticizers and other common admixtures. We recommend compatibility testing for specific mix designs.

3.Will the defoaming agent affect concrete setting time?

ʻIkai, when dosed properly, our defoaming agent will not significantly affect concrete setting time or cement hydration, ensuring normal construction progress.

4.What is the recommended dosage and usage method?

The dosage is 0.01% - 0.3% 'i he mamafa 'o e sima. Powder type is dry-blended with other dry ingredients, while liquid type is added directly to the concrete mix and stirred evenly. We suggest laboratory tests to confirm the optimal dosage.

5.'Oku ke 'oatu 'a e ngaahi me'a fakamamani lahi mo e poupou fakatekinikale .?
