Contrary to what the current name indicates, the function of air entrainers is not to generate air voids but to stabilize the mechanically entrained air during mixing. Therefore, air void content is dependent on the mixing process and can vary depending on mixing device, mixing duration, time of mixing, temperature and the additives used.
Advantages of synthetically produced air entrainers
There are a variety of different air-entraining agents on the market, consisting of natural active ingredients, synthetic surfactants and mixtures. Our synthetically produced air entrainers do not suffer from quality fluctuations associated with natural active ingredients. They offer consistent quality, are more stable and therefore more reliable. Synthetic air entrainers are characterized by the fact that dosage and entrained air correlate. On the other hand, air entrainers based on natural active ingredients, increase the air content at high dosages disproportionally. The increase in efficiency of synthetic air entrainers ensure optimized construction costs and resource efficiency.
Ideally buildings are built to last. However, many buildings frequently require maintenance after only a few years. Air entrainers from the SITREN AirVoid® range provide increased durability and the option of efficient lightweight construction and improved processing, thus optimizing construction costs and the entire life cycle management of a building. Ideal for the manufacture and processing of air-entrained concrete, in accordance with EN 1992 EC2.
