Batimix AEA-110

Description

BATIMIX AEA-110 is an aqueous solution of modified resins and surfactants. It is used as an air-entraining admixture for all types of concrete.

Main Purpose

BATIMIX AEA-110 is designed to produce air-entrained concrete for increased durability and resistance to damage by frost and de-icing salts. It is also used to improve the cohesion and workability of concrete. It is used in concrete produced from poorly graded aggregates or when bleeding and segregation phenomena occur.

Applications using BATIMIX AEA-110 include concrete castings such as plain, reinforced, paving, ready-mixed, pumped, and lightweight, particularly when exposed to freeze/thaw conditions.

Features

Concrete prepared with BATIMIX AEA-110 is characterized by the following:

In the plastic state:

• Controlled quantity of evenly distributed microscopic air bubbles
• Enhanced cohesion and resistance to bleeding as less water is used
• Improved workability, as air bubbles reduce internal friction

In the hardened state:

• Increased resistance to attack by sulfate, frost, corrosive water, and de-icing salts
• Reduced absorptivity, as air bubbles act as air plugs
• Limitation of progressive cracks, as air bubbles dissipate energy at their tips
• Improved overall concrete durability and surface appearance

Properties

• Appearance: brown liquid
• Specific gravity: 1.01 ± 0.02 at 23 ºC
• Chloride content: nil
• Alkali content: typically, less than 1.5% as Na₂O

Health and Safety

BATIMIX AEA-110 is not a hazardous material. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.

Compliance with Standards

BATIMIX AEA-110 complies with the following standards:

• EN 934-2:T5
• ASTM C260

Effect of Overdosing

An overdose of BATIMIX AEA-110 will result in an increase in air entrainment which may significantly reduce strength. The degree of this effect will depend on the particular mix design and overdose level. The increased air content from an overdose will generally tend to lead to an increased plasticizing effect.

Compatibility

BATIMIX AEA-110 is compatible with all other Batimix admixtures incorporated in the same concrete. During batching, all admixtures should be added separately to the concrete mix as this may alter their performances.

Concrete mixtures based on Portland cement with or without replacement materials such as silica fume, fly ash, and blast furnace slag are compatible with BATIMIX AEA-110.

Dispensing

Automatic dispensing systems should preferably be used to introduce the correct quantity of BATIMIX AEA-110 in the concrete mixer. This admixture should be added at the beginning of mixing, i.e. after incorporating around 1/3 of the mixing water along with the aggregate particles. It should not be introduced on the dry cement.

Technical Support

Holderchem provides, upon request, technical advisory services for concrete mix design, admixture selection, materials testing, and dispensing system.

Storage

BATIMIX AEA-110 has a minimum shelf life of 12 months if kept unopened and stored at temperatures ranging from 2 to 50 ºC.
