HBM (Hydraulically Bound Material)

HBM (Hydraulically Bound Material) is the generic name for a family of products, these include:

Cement Bound Granular Material (CBGM) (BSEN 14227-1). CBGM is used in road, airfield, port, and other heavy-duty pavement construction projects. It is affordable and a great sustainable alternative to asphalt construction.

Fly Ash Bound Material (FABM) (BSEN 14227-3). Fly Ash bound mixtures is used in the construction of pavements. It is also used in the road construction because it is versatile and high performing.

Slag Bound Material (SBM) (BSEN 14227-2). Flushing SBM uses the hydraulic combination of granulated blast furnace slag and air-cooled steel slag/concrete. It is widely used in the construction of highways where thickness and strength are required.
