Purchasing Air‑Entraining Admixture for Concrete

When it comes to construction projects in cold and humid regions, purchasing CB10 Air‑Entraining Admixture is a professional and essential choice. Thanks to its unique properties, this product meets the needs of infrastructural, civil, road, and urban construction projects.

When selecting this admixture, it is important to carefully evaluate climatic conditions, concrete type, cement content, and execution methods to achieve optimal results.

Furthermore, the brand and manufacturer’s credibility play a vital role. Fortunately, companies such as ZORLU Chemical produce high‑quality, standardised products, making it possible to source reliable concrete air‑entraining admixtures for professional projects. In some construction applications, accessories like waterstops are also used alongside CB10 Air‑Entraining Admixture to ensure precise control over water and additive dosing.


Properties and Effects of CB10 Air‑Entraining Admixture

Using CB10 offers multiple technical and practical benefits clearly visible in the final concrete quality.

Its most important feature is enhanced resistance to freeze‑thaw cycles, preventing surface cracking and scaling in cold climates.

By creating a uniform but well‑distributed porous structure, the admixture reduces concrete permeability and increases long‑term durability. Other benefits include:

  • Improved workability without adding extra water
  • Reduced bleeding and aggregate segregation
  • Maintained concrete integrity
  • Reduced formation of capillary pathways for water and harmful ions

Practical Applications of CB10 Air‑Entraining Admixture

CB10 is widely applied in various construction sectors, from roadworks to special‑purpose structures. In surfaces such as airport runways, highways, cold storage floors, and bridge decks – subjected to extreme temperature and moisture fluctuations – its use significantly increases the service life of the structure.

It is also highly beneficial in concrete placements for dams, water reservoirs, irrigation networks, and even precast products such as Jersey barriers and curbstones. Another important application is in concretes with high lime content, where CB10 still delivers excellent results.


Safety and Storage Guidelines

As with all chemical concrete admixtures, safety measures must be followed when working with CB10:

  • Wear protective gloves and safety glasses during mixing and handling to avoid skin or eye contact.
  • If skin irritation occurs, seek medical attention.

Storage conditions:

  • Store between +10 °C and +30 °C
  • Keep away from frost, direct sunlight, and excessive heat
  • Prevent freezing
  • Keep in original packaging for a maximum of 12 months

Packaging options:

  • 20 L jerrycans
  • 220 L drums
  • 1000 L IBC tanks

Recommended Dosage

The dosage of CB10 depends on several factors such as cement type, environmental conditions, and project objectives.

For achieving 4–6% entrained air in concrete, the recommended range is 0.2% to 0.5% of cement weight.

Several factors may influence the final air content, including:

  • Increased cement content or fineness
  • Ambient temperature changes
  • Pumping operations

Field testing is essential to determine the exact required dosage for any specific project to ensure performance is not compromised.


Mechanism of Action

CB10 contains molecules with a long hydrocarbon chain at one end and a polar group at the other.

  • The polar end is attracted to water
  • The non‑polar end is attracted to air

This arrangement stabilises microscopic air bubbles in the concrete mix, preventing them from merging or escaping during mixing and placement.


Storage and Shelf Life

Shelf life: Up to 1 year in unopened original packaging.

Environment:

  • Dry, protected from frost, excessive heat, and direct sunlight
  • Ideal storage temperature: +10 °C to +30 °C

Manufacturer’s instructions should always be observed to ensure optimal performance and to prevent waste due to property changes.


Applicable Standards

  • ASTM C233
  • ASTM C260
  • ASTM C666

All of these properties make CB10 a stable, concrete‑compatible, and highly reliable admixture for professional construction applications.

Method of Use for CB10 Air‑Entraining Admixture

Proper use of CB10 Air‑Entraining Admixture requires adherence to technical principles to ensure that air bubbles are distributed stably and uniformly throughout the concrete.

  1. Dilution:

    Begin by diluting the admixture with twice its volume of mixing water.

  2. Addition:

    Slowly add the diluted solution to the concrete during mixing.

  3. For Ready‑Mix Concrete:

    If adding the admixture to already batched concrete, ensure that thorough mixing is carried out so the product disperses evenly.

  4. Important Precaution:

    CB10 Air‑Entraining Admixture must never be poured directly onto dry cement or cement powder, as this can reduce performance and cause undesirable chemical reactions.
