Generally mat shaped concrete construction units provide novel, versatile building materials particularly for flexible multi-ply concrete composites in pavement or floor construction, roadbeds, driveways, waste disposal sites, etc. The mat-like structures comprise an outer shell subdivided into parallel tubular compartments which are filled with dry concrete mix so as to provide controlled chemical hydration for greater strength and durability. The multi-ply structures fabricated with the concrete construction units exhibit enhanced resistance to fracturing and possess residual structural values not found in equivalent poured concrete structures.
