In-Situ Generation of Polymer Concrete Construction ...

With this goal in mind, researchers at Luna have identified a polymer concrete formulation based on urea-formaldehyde (UF) that can be pressed into high compressive strength interlocking bricks suitable for construction. Luna?s binder system can also be produced in-situ from feed gases identified by NASA (N2, H2, CO2) while generating O2 and water.

Polymer Concrete as Construction Materials

Since 1950s, there has been increasing interest on concrete-polymer composites as new construction materials in the construction industry. The concrete-polymer composites, typically, can be classified into three types in terms of principles of the process technology, i.e. polymer cement concrete, polymer concrete, and polymer impregnated concrete.
