DMAT, an Italian cleantech company founded in 2021, develops sustainable and durable concrete building materials. The concrete has a notable ability of self-healing. This not only extends the material's lifespan but also reduces maintenance costs and further deterioration, thereby reducing CO₂ emissions.
Challenges: concrete CO₂ emissions
Concrete is one of the most widely used materials in the world for construction, owing to its durability and versatility. However, despite its robust nature, concrete is subject to deterioration and aging over time, particularly after the initial casting or molding process. As a result, regular maintenance is essential to ensure the longevity and structural integrity of concrete structures. This regular maintenance increases cost and carbon dioxide (CO₂) emissions.
A common problem with concrete is that it cracks, which can be dangerous if not fixed. As soon as cracks appear, they let harmful things like air, moisture, and chemicals into the concrete matrix. This speeds up the breakdown process. This makes the concrete less effective and raises the risk of the structure failing. This shows how important it is to fix and reinforce things as soon as possible to lower these risks and keep infrastructure safe.
DMAT Technology
DMAT has developed a specific concrete mixture comprising calcium oxide (CaO). The concrete exhibits improved self-healing without a detrimental reduction in concrete workability or compressive strength. This building material not only enables less building maintenance and longer building life but also lowers CO₂ emissions.
