How to Make Air Entrained Concrete

Air content of the freshly mixed concrete can be measured by gravimetric, volumetric, or pressure methods. The pressure method is the most commonly used, and in this method a calibrated air meter is used to test a known volume of concrete that is subjected to a defined pressure. Slump and Concrete Strength of Air Entrained Concrete

Concrete Testing Information

Air-entrained concrete is typically specified in areas of the country where frost-related damage can occur. The measurement of air content in fresh concrete of normal density is typically performed using the pressure method . Another useful test is ASTM C 173. However, the pressure method is frequently preferred because it is relatively fast.

Cement Concrete Testing Equipment

The ROLL-A-METER is a simple device for measuring entrained air in freshly prepared concrete by using the rolling or washout method. The meter is for use with any type of aggregate (dense, cellular, or lightweight) not exceeding 2". The capacity of the meter is 130 cu. in. in the base section.

Foam Concrete: A State-of-the-Art and State-of-the-Practice

Foam concrete (FC) has the potential of being an alternative to ordinary concrete, as it reduces dead loads on the structure and foundation, contributes to energy conservation, and lowers the cost of production and labor cost during the construction and transportation. The paper reports a state-of-the-art review of foam concrete in terms of its components, manufacturing and material properties ...

Air Pressure Meter | Deslauriers, Inc

The test method equalizes a known volume of air in the pressure chamber, with the unknown value of entrained air in the meter’s concrete filled base. The amount of entrained air is then read on the meter’s gauge as the direct percentage of air entrained in the sample. Constructed of cast aluminum, the meter is durable yet lightweight.

Pros and Cons of Air-Content Measuring Methods

Small variations in specific gravity or large variations in mix proportions can again cause relatively large errors in air content. The volumetric test requires diluting the concrete with water, then repeatedly rolling and agitating the volumetric air meter to free the entrained and entrapped air.

This is ...

Entrained Air - an overview

21.5 Mix design for air-entrained concrete 21.5.1 Effect of air entrainers. Air entrained mixes are produced with the addition of an air entraining admixture, and are normally used to prevent freeze–thaw damage. The air entrainer will improve the workability and reduce the strength and the density (see Section 24.4). 21.5.2 UK practice

Testing for Air in concrete| Concrete Construction Magazine

The only ingredient in the concrete that is compressible is the air. Cementitious material, water, and aggregates do not respond to the small rise in pressure. So the pressure change is correlated to the air content of the concrete. Entrained air is formed in concrete using a surfactant. The smaller the bubble, the stronger the bubble.

Air Entrainment versus Air Entrapment - NPCA

“Your predicament brings up a few questions; however, the answer is the same as for standard concrete. Mixing an air entrained mix with a non-air entrained mix will lead to a reduced air entrainment effectiveness. You did not mention the circumstances that led to this “mix mixing.”

Air entrainment

Air entrainment is the intentional creation of tiny air bubbles in concrete. A concrete maker introduces the bubbles by adding to the mix an air entraining agent, a surfactant (surface-active substance, a type of chemical that includes detergents). The air bubbles are created during mixing of the plastic (easy flowing, not hardened) concrete ...
