Sandwich wall

The precast sandwich wall (w) is made of two layers of concrete with isolation in between and the sandwich wall is an exterior wall in buildings. The inner concrete layer is load -bearing while the outer concrete layer can resist moister and mould. Every sandwich wall produced is tailored based on the customer’s specific requirements, therefore the structure of the wall surfaces varies based on the orders placed. 

All products are manufactured indoors, which ensure a high and even quality. Therefore, sandwich wall can have a life span up to 100 years. The maintenance required for the sandwich wall is low during its lifespan and also our product meets all the necessary requirements for moisture, acoustics and fire protection. 

During the use phase, cementitious materials (hydration products in the concrete) present on the exterior surface of the wall chemically reacts with the atmospheric carbon dioxide due to carbonization and calcium carbonate is formed as the result. However, the carbonization is not taken into the account in this study.
