Shock-absorbing block

Shock-absorbing blocks for bullet stops at firing ranges and for traffic control are made by encasing scrap rubber tires in concrete. To ensure firm attachment of the tires to the concrete, reinforcements such as wire loops are fastened to the tire. To prevent the formation of air pockets during the...

Zusammenfassung:	Shock-absorbing blocks for bullet stops at firing ranges and for traffic control are made by encasing scrap rubber tires in concrete. To ensure firm attachment of the tires to the concrete, reinforcements such as wire loops are fastened to the tire. To prevent the formation of air pockets during the pouring of the concrete mixture into a mold holding the tire, vent holes are punched into the side walls of the tire. To allow the concrete mixture to flow under the tire in the mold, the tire is propped up with support blocks. Wires may be strung across the top of the tire and attached to the side walls of the mold to prevent movement of the tire while the concrete is being poured into the mold. The concrete mixture may contain an aqueous foam additive, a stabilizer, and fiber reinforcements such as steel or organic polymers.
