HydraPressed Concrete Paving Slabs. HydraPressed Concrete Paving slabs are made from a concrete mix, using a 700 ton hydraulic press at intense pressures exceeding 2250 PSI. This process creates a product of high density and durability together with a surface comparable to that of natural stone. The compressive strength of the slabs if 8000 PSI.
Decomposed granite, in a crushed stone form, is used as a pavement building material. It is used on driveways, garden walkways, and municipal urban park and natural regional and national park ''sidewalks'' and heavyuse paths. Decomposed granite paving specifications and granite effect paving "flags" or cobbles in the UK, would depend on the material available and the use to which it is to be put.
Understanding Grades of Concrete. Grades of concrete are defined by the strength and composition of the concrete, and the minimum strength the concrete should have following 28 days of initial construction. The grade of concrete is understood in measurements of MPa, where M stands for mix and the MPa denotes the overall strength.
