Chemical Admixtures

Air entraining chemicals should never be mixed with any other chemical additives. Figure 4. Mode of action of an air-entraining agent . Just providing an adequate air content inside concrete is not sufficient. Small and stable air bubbles are required for efficient protection against freezing and thawing.

Admixtures for Concrete - Civil Engineering

ods. An air-entraining cement is a portland cement with an air-entraining addition interground with the clinker during manufacture. An air-entraining admixture, on the other hand, is added directly to the concrete materials either before or during mixing. The primary ingredients used in air-entraining ad-mixtures are listed in Table 6-1 ...

Air entrainment - Wikipedia

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, and most of them survive to be part of the hardened ...

Controlling Oil Aeration and Foam

Foam and air entrainment problems are quite common, but are traditionally hard to treat. Previously, the standard procedure was to run an ASTM D892 foam test on the offending oil, and then indiscriminately add an aftermarket additive, usually silicone-based. Generally foam went away quickly, only to ...

How to Use Air-Entrained Concrete ... and Why You Should ...

The strength of air-entrained concrete depends on the water/cement ratio as it does in non-air-entrained concrete. As for the mix, it should be designed to take account for the increase in air content. The water content for an air-entrained mix will be 3 to 5 gallons per cubic yard less than for a non-air-entrained mix having the same slump.

Air entraining agents - ScienceDirect

Concrete always contains a (more or less important) volume of air bubbles. These bubbles are formed during the mixing of concrete. In the absence of an air entraining agents (AEA) or a contaminant that entrains air, the total volume of air entrapped in concrete is usually between 1% and 3%.

Perlite and vermiculite concretes require air entrainment of some type. The use of the correct amount of air entraining agent is very important. Air entraining agents (essentially special industrial soaps and/or foaming agents) produce countless tiny air bubbles that reduce the density of the concrete, increase the yield, and contribute to the ...

Abstract. This paper presents the test results of air entrained concrete mixtures made at a constant W/C ratio of 0.44. Three different air entraining agents were used: polymer microspheres, glass microspheres and a conventional air entraining admixture. The aim of this study was to compare the effectiveness of the air entraining methods.
