MAPEI AS PATRON AND SUPPLIER
There is a long tradition in Austria that every tunnel construction receives a patron. It goes back to the legend of Saint Barbara, who once had to flee from her tyrannical father. God opened up a crevice in the rock face so that she could hide in it. Since then, she has been the patron saint of miners. According to the custom, a tunnel patron is the earthly representative of Saint Barbara. She is meant to bring good luck to the project and the workers during the construction phase.
At the Fröschnitzgraben, this honour was awarded to Andrea Kapoun, Marketing Manager at Mapei GmbH (Austria). A bit of luck is always handy. Above all, however, skill and the perfect interaction of all participating companies are required.
This is why Mapei admixtures for concrete and the Mapei mobile laboratory are both present on site to ensure the proper concrete mix is achieved.
An incredible 850,000 m3 of concrete is required for the works in Fröschnitzgraben – all of it processed by Mobil Baustoffe GmbH, a worldwide leading specialist in large construction projects and a Mapei partner.
Among the chosen admixtures one finds: DYNAMON RC520* and DYNAMON LZ SP W20*, two polycarboxylate-ether-based superplasticizers, DYNAMON LZ553*, a plasticizer used to extend the workability of concrete, MAPEAIR LP 100*, an air entraining agent for freeze-resistant concrete, and the retarding agent MAPETARD VZM*. All these products are distributed on the Austrian market by Mapei GmbH (Austria).
