Bio-aerated autoclaved concrete for sustainable building

For achieving the objectives:

Goals: 9. Industry, innovation & infrastructure, 11. Sustainable cities and communities

Description

ENEA makes available its know-how on an innovative technology to develop cellular concrete, a product particularly suitable to be used in developing countries thanks to its good thermal insulation properties. This technology exploits the reaction between the enzymes contained in microorganisms (yeasts) and hydrogen peroxide to generate the aeration process needed to produce cellular concrete.

Benefits and Advantages:

Highly environmentally-friendly
Simpler and better industrial fabrication process
Enhanced technical properties of the product
Cost saving

ENEA Service:

Consulting on the possible product applications
Design

ENEA Activities:
