Paving brick gains its strength through virtification, a process that makes brick impervious to water. The term vitrified when applied to brick means that a chemical action has coalesced the clay particles and fused them with heat to form a near-liquid substance, which then slowly hardens over a seven- to ten-day period. A thoroughly vitrified brick has no visible pores and breaks with a smooth fracture. The crushing strength of good quality paving brick is eight to ten thousand pounds per square inch. In comparison, concrete has a strength of thirty-five hundred pounds per square inch.
Historical Bricks has salvaged these beautiful antique street pavers from streets throughout the MidWest. These bricks are perfect for walkways, drives, patios, and also can be used in walls.
