AIR-ENTRAINING AGENTS
ALPHALITH® IS A HIGHLY EFFECTIVE, UNIVERSALLY APPLICABLE AIR ENTRAINING AGENT FOR MORTAR AND CONCRETE
Air-entraining Agents ALPHALITH®
Our air entraining agents for use in road construction, bridge construction and prefabricated parts.
For concrete made from low fine grain mixtures and concrete that comes into contact with the effects of frost and de-icing salt.
Air entraining agents create a system of tiny, self-contained micropores in the concrete. This pore system serves as an expansion space for freezing water and thus significantly increases the resistance of the concrete to the damage caused by frost and de-icing salt.
In addition, the micropores interrupt the capillary suction effect and reduce the atmospheric water absorption of the concrete. In fresh concrete, the micro-air pores cause a ball bearing effect and thus significantly improve workability.
 In low fine grain mixtures, the micro-air bubbles replace the missing fine grains to some extent.

ALPHALITH® Micropor 95 (LP)
Product:
ALPHALITH® Micropor 95 (LP) is a liquid, resin-based air entraining agent. Its concentration allows an exact dosage in order to achieve constant contents of air bubbles.
alphalith Micropor 95 LP generates small an stable air bubbles in the concrete, which act as ball bearings in the fresh concrete, thus improving workability. The air bubbles also act as a substitue for lacking fines in the aggregate.
In the hardened concrete the micropares formed by the air bubbles interrupt the capillary water suction and hence reduce the capillary water suction of the concrete. Freezing water ist allowed to expand into the micropores. This leads to a substantial improvement of frost-thaw-resistance.
Features:
- creates a system of stable micropores of defined size and distribution in concrete
- increases flexibility
- improves workability
Fields of Application:
- concrete with high freeze-thaw resistance
- concrete with high resistance to freez-thaw with de-icing salts
- concrete with low contents of fines in the mix
- pumped concrete
- lightweight concrete blocks
ALPHALITH® Micropor S (LP)
Product:
ALPHALITH® Micropor S (LP) is a liquid, resin-based air entraining agent. Its concentration allows an exact dosage in order to achieve constant contents of air bubbles.
alphalith Micropor S LP generates small an stable air bubbles in the concrete, which act as ball bearings in the fresh concrete, thus improving workability. The air bubbles also act as a substitue for lacking fines in the aggregate.

- concrete with high resistance to freez-thaw with de-icing salts
- concrete with low contents of fines in the mix
- pumped concrete
- lightweight concrete blocks
ALPHALITH® Micropor T (LP)
Anwendung:
ALPHALITH® Micropor T (LP) is used in concretes that come into contact with frost and de-icing salt. The areas of application are therefore in road and bridge construction, in the manufacture of concrete products (e.g. stair embankments) and wherever the workability of low-powder contents mixtures is to be improved.
In the hardened concrete the micropares formed by the air bubbles interrupt the capillary water suction and hence reduce the capillary water suction of the concrete. Freezing water ist allowed to expand into the micropores. This leads to a substantial improvement of frost-thaw resistance.
Featurs:
- increase of freeze-thaw resistance
- creates a System of stable micopores of defined size and Distribution in concrete
- for precast elements (barrier walls, steps, etc.)
- improves workability and reduced bleeding
- recommended for combination with PCE-based superplasticizers
