Airkem Air-Entraining Additive

Airkem is a chloride-free air-entraining admixture for use in lightweight ready-mix concrete and mortar. Developed for concretes and mortars that require lower density and easier handling.

Aditivo incorporador de ar na fabricação de concreto

Airkem is an additive that incorporates air in a predictable way for the production of stabilized mortar and other types of lightweight concrete.

It can be used with the same equipment used in regular concrete production, respecting the appropriate mixing and material dosage conditions. The mortar must contain an adequate amount of mixing water to allow for proper air incorporation. Furthermore, mixing conditions, considering time, speed, and maintenance of the mixer drum blades, are important to obtain maximum and stable air incorporation throughout the transport and placement of the stabilized mortar and lightweight concrete.

Air-entraining additive

Airkem is used as an air-entraining admixture in concrete batching plants for the production of :

  • Lightweight concrete with a unit mass of up to 1,600 kg/m³ (depending on materials, temperature and mixing conditions);

  • Stabilized mortar;

  • Controlled density terrain;

  • Subfloor filling ;

  • Improved thermal and acoustic comfort;

  • Concrete and mortar for filling and raising;

  • Filling in ditches, mines and contaminated soils;

  • Other types of lightweight concrete and mortars.

What are the advantages of using Airkem air-entraining additive?

Airkem caters to a wide range of applications in the production of lightweight concrete and mortars. The main advantages of its use are listed below:

  • It allows the production of mortars and concretes with lower densities than conventional ones;

  • Using the same equipment available at the plant, it is possible to produce lightweight concrete and stabilized mortars;

  • It promotes characteristics in mortars and concretes that provide greater acoustic and thermal insulation, as well as lower load on structures due to its reduced specific mass;

  • Promotes increased fluidity and ease of finishing for lightweight concrete and stabilized mortar;

  • Stability during storage without sediment formation or clogging of tank dispensers and valves.
