Air-entraining Admixtures

Proper air-entrainment in concrete is key to creating better mix designs that results in more workable concrete.

Overview

With GCP air-entraining admixtures, air is incorporated into the concrete by the mechanics of mixing and stabilized into millions of discrete semi-microscopic bubbles in the presence of a specifically designed air-entraining admixture. These air bubbles act much like flexible ball bearings increasing the mobility, or plasticity and workability of the concrete. This can permit a reduction in mixing water with no loss of slump. Placeability is improved. Bleeding, plastic shrinkage and segregation are minimized.

DARAVAIR®

DARAVAIR® is a liquid air-entraining admixture that provides freeze thaw resistance, yield control and finishability performance across the full range of concrete mix designs. Through the purposeful entrainment of air, DARAVAIR® markedly increases the durability of concrete to severe exposures particularly to freezing and thawing. It has also demonstrated a remarkable ability to impart resistance to the action of frost and de-icing salts as well as sulfate, sea and alkaline waters.

AIRALON®

AIRALON® is widely used as an air-entraining and plasticizing agent for masonry cement and as an air-entraining agent for air entrained Portland cement. AIRALON® is interground during the manufacture of these cements. Entrainment of air is accomplished by the development of a system of semi-microscopic bubbles introduced into the mix by agitation and stabilized by AIRALON® in the paste phase of the mortar or concrete.

DAREX®

DAREX® AEA admixture is an aqueous solution of a complex mixture of organic acid salts. DAREX® AEA is specially formulated for use as an air-entraining admixture for concrete and is manufactured under rigid control which provides uniform, predictable performance. It is supplied ready-to-use and does not require pre-mixing with water. Because DAREX® AEA imparts workability to the mix, it is particularly effective with slag, lightweight, or manufactured aggregates which tend to produce harsh concrete. It also makes possible the use of natural sand deficients in fines.
