I PAGE 3 NEWS Standardization UHPCs enter the industrial age Industrial companies’ investments in engineering, sustained by the commitment and innovation of designers and project owners, has enabled ultra-high performance concretes (UHPCs) to demonstrate their superior capabilities. Today, UHPCs require a technical and legal framework tailored to their volume growth and diversity of their applications. The standardization work now in progress should improve projects’ insurability over the short term by providing recognized and shared reference systems. THREE-FOLD Ultra-high performance concretes are the these new concretes.
