Ozone_AEA.pdf – Downloaded 116 times – 407.06 KB| Description | Ozone AEA is a chloride free air-entraining and water reducing admixture based on synthetic surfactant and special polymer. Ozone AEA acts at the interface between the mixing water and cement/aggregate particles to produce microscopic air bubbles, which are evenly distributed throughout the concrete. The entrained air enhances durability by protecting the rapid temperature changes found in freezing and thawing conditions and with the use of de-icing salts. |

| Primary Application | Roads and bridge decks, airport runways and taxiways, and other concrete exposed to potential frost damage. To improve cohesion and workability of concrete mixes where poorly graded aggregates must be used and bleeding, segregation, or sand runs occur. |
||||||
| Advantage | Air entrainment increases the resistance of concrete to attack by frost and de-icing salts, reducing problems of surface scaling and concrete failure. Entrained air bubbles assist in the formation of a stable cohesive mix, reducing segregation and bleeding. Air entrainment improves workability and helps produce a dense, uniform, close textured surface free from gravel nests and sand runs, further enhancing durability. Excellent air bubble stability allows use with a wide range of aggregate qualities and mix conditions. Typical dosage levels are higher than for standard air-entraining admixtures, allowing increased accuracy of dosing and better control in critical situations. Synthetic basis reduces the potential for incompatibility problems during dispensing of admixture combinations. |

| Instruction for use | Dosage: 0.4-0.8 Ltr/100kg of cement. It is advisable to carry out trial mixes to establish the exact dosage rate required. Dispensing: Ozone AEA should be added to gauging water before its addition to the dry mix concrete or separately to the freshly mixed concrete. When added separately to the freshly mixed concrete further mixing time of 2-3 minutes should be given. Placing: The standard rules of good concreting practice for production and placing must be observed when using Ozone AEA concrete. Curing: Fresh concrete must be cured properly. Use Ozone Curecrete or wet hessian. Compatibility: Ozone AEA is compatible with all types of cement. Effect of overdosing: When accidental overdosing occurs, the retardation of initial set air content and workability increases. During this period the concrete must be kept moist to prevent premature drying out. |
