Claim 1
Independent Claim
87 words
THE METHOD OF PREPARING A MATERIAL USEFUL FOR CONSTRUCTION COMPRISING THE STEPS OF: A. CRUSHING GLASS BOTTLES AND THE LIKE; B. FORMULATING A MIXTURE OF COARSE, MEDIUM AND FINE AGGREGATE HAVING A VOID VOLUME NOT IN EXCESS OF 20 PERCENT C. FORMING SAID MIXTURE AND A MONOMER SELECTED FROM THE GROUP CONSISTING OF STYRENE, METHYL METHACRYLATE, ACRYLONITRILE, ISOBORNYL METHACRYLATE, AND TRIMETHYLOLPROPANE TRIMETHACRYLATE WITH ADDITIVE INTO THE DESIRED SHAPE; D. VIBRATING THE MIXTURE CONTAINING MONOMER TO ELIMINATE TRAPPED AIR; AND E. CAUSING IN SITU POLYMERIZATION OF SAID MONOMER.

Claim 3
Dependent Claim
33 words
The method of claim 1 in which the mixture is formulated of about 60 percent by weight of coarse aggregate, about 25 percent by weight of medium aggregate, and the remainder fine aggregate.
Claim 4
Independent Claim
122 words
The method of manufacturing a sewer pipe comprising the steps of: a. crushing glass bottles and the like; b. formulating a mixture of coarse, medium and fine aggregate in which the void volume is not in excess of 20 percent; c. pouring the mixed glass into a form including a pair of concentrically arranged cylindrical forms; d. impregnating the mixed glass with a monomer selected from the group consisting of styrene, methyl methacrylate, acrylonitrile, isobornyl methacrylate, and trimethylolpropane trimethacrylate containing a chemical catalyst; e. vibrating the mixture impregnated with monomer to eliminate trapped air; and f. blowing warm air along the walls of said forms to maintain a proper elevated temperature for a sufficient length of time to cause in situ polymerization.
