Abstract

A wet concrete recycling system for mixing trucks returning to the cement plant throughout the workday. “Residual-collection” molds, kept on-hand at the plant, are filled with any excess wet concrete present in the returning trucks. The molds are configured to form finished components such as roadway barrier sections (i.e. jersey walls), and the like. The finished components are low in cost due to the use of recycled wet concrete, inexpensive reinforcing materials, and handles / assembly elements fabricated from other recycled materials. The finished components may be sold or leased to customers, thereby converting costs typically associated with traditional residual concrete disposal techniques into supplemental income streams. The finished components may be assembled into continuous roadway safety barrier walls. All structures assembled from two or more of the finished components are inexpensive due to the low cost of the individual components, easily constructed, and may be permanent or temporary in nature.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is related to U.S. Provisional Application Ser. No. 60 / 535,450, filed 8 Jan. 2004, entitled “System for recycling wet concrete into precast structures and structures formed thereby.”BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to efficiently recycling concrete waste from ready-mix cement trucks. More particularly, the present invention relates to roadway barrier components formed using a system for recycling excess wet concrete, and means for assembling the individual components into a continuous safety barrier wall.

[0004] 2. Discussion of the Background

[0005] Often times ready-mix concrete trucks return to the cement yard at the end of the workday with relatively large amounts of excess fresh concrete. This excess fresh concrete must be disposed of or recycled in some manner, so that the cement trucks may be cleaned for the next day's operations.

[0006] The typical...

Examples

Embodiment Construction

[0038] The present invention is pre-cast roadway barrier components fabricated of the recycled excess or residual wet concrete remaining in ready-mix concrete trucks after completion of a job, and the means for assembling the individual components into a continuous safety barrier wall.

[0039] The recycling of the excess or residual wet concrete begins with the mixing trucks returning to the plant during and at the end of the workday. “Residual-collection” molds are kept on-hand at the plant, and as the ready-mix cement return they evacuate their excess wet concrete into the residual-collection molds. The molds are configured to form pre-cast structural components such as roadway barrier sections, and the like.

[0040]FIGS. 1 and 2 are, respectively, plan and cross-sectional views of a casting bed 15 including a plurality of molds 18 used to create roadway barrier sections according to a preferred embodiment of the present invention.

[0041] As stated above, at the end of a workday it ...
