DAREX® AE3 is a liquid air-entraining agent for use in the production of air entrained concretes, blocks and cement compositions.
DAREX® AE3 is formulated from carefully selected raw materials and is manufactured under controlled conditions. It is based on the salt of an ether sulfate and conforms to EN 934-2, for air-entraining admixtures.

DAREX® AE3 is supplied ready for use. It should be added to concrete or mortar mixtures during the mixing process at the same time as the water or with the aggregates. The amount of DAREX® AE3 required is dependent on the characteristics of the concrete concerned and the level of air entrainment required. Factors which affect this are:
With Cements :
DAREX® AE3 can be used with most types of Portland cements. It is also effective in concrete containing fly ash or ground granulated blastfurnace slag. For use with special cements we recommend that you consult GCP Applied Technologies.
With Other Admixtures:
DAREX AE3 should not under any circumstances be premixed with other admixtures. The performance of the product will be affected by the presence of other chemical admixtures. We recommend that all admixtures be added separately into the mix.
| Range | 30 ml - 180 ml per 100 kg cement |
| 0.03% -0.18% (v/w) by wt. of cement | |
| As a guide to trials an addition rate of 0.06-0.18% volume by weight of cement is suggested. | |
| For advice and assistance with trials we recommend that you consult GCP Applied Technologies. | |
It is essential that the final assessment of the dosage should be made after the site trials. As a guide to these trials, the addition rate will then determine the target requirement dependent of the contributing factors stated (where DAREX® AE3 is used in concretes containing fly-ash, the dosage rate may typically be twice the range quoted above). For semi-dry mixtures 280ml - 400ml DAREX® AE3 per 100kg
cement is suggested.
The effect of overdosing DAREX® AE3 is a function of the degree of overdose. Overdosing with DAREX® AE3 will produce an increase in air content and workability.
It is preferable that DAREX® AE3 should be introduced into the mixer by automatic dispensing equipment. Equipment or advice on dispensing can be obtained from GCP Applied Technologies.
For further information on Health and Safety matters regarding this product we recommend that you consult the relevant Material Safety Data Sheet from GCP. In line with general chemical handling precautions avoid contact with skin or eyes and protective gloves/goggles should be worn.
