MCFR (mineral composite fiber reinforced)

Recommended Posts

A new construction method featuring LEGO-like bricks made from a renewable composite material took first place for building innovations at the 2024 JEC Composites Innovation Awards in Paris, France.

RENCO USA's RENCO MCFR (mineral composite fiber reinforced) building system is composed of interlocking molded blocks similar to LEGO bricks. According to the maker, the system surpasses concrete in strength, reduces costs significantly, and allows for rapid construction. Made with recycled glass fibers, resin, and stone, the composite material is certified to withstand Category 5 hurricanes.

Following more than 12 years of research and development, RENCO completed its inaugural apartment complex in Palm Springs, Fla., last November. No specialized workers or heavy machinery are required to build with the blocks that are stronger but 75% lighter than concrete. 

In Palm Springs, 11 unskilled workers, following color-coded plans, assembled each three-story building in about eight weeks.
