Abstract

A concrete block mixture includes Portland cement, a natural aggregate filler, water, and a quantity of particularly sized glass particles. The associated method of producing blocks from the mixture eliminates the need of curing the blocks in a heated humidity controlled environment in order for the blocks to attain the required water content for hydration of the cement.

Claims

exact text as granted — not AI-modified
1 . A concrete block mixture comprising:
 approximately 10 to 15% by weight of Portland cement;   approximately 65 to 80% by weight of a natural aggregate filler;   approximately 5 to 10% by weight of water; and   approximately 8 to 15% by weight of glass particles the majority of which have a particle size of 50 mesh or smaller.   
     
     
         2 . The mixture of  claim 1  wherein 45% to 50% of the glass particles have a size greater than 100 mesh. 
     
     
         3 . The mixture of  claim 2  wherein 5% or less of the glass particles have a size greater than 50 mesh. 
     
     
         4 . The mixture of  claim 3  wherein 10% or less of the glass particles have a size smaller than 300 mesh. 
     
     
         5 . The mixture of  claim 4  wherein at least 70% of the glass particles have a size of 50 mesh or smaller. 
     
     
         6 . The mixture of  claim 2  wherein 10% or less of the glass particles have a size smaller than 300 mesh. 
     
     
         7 . The mixture of  claim 6  wherein at least 70% of the glass particles have a size of 50 mesh or smaller. 
     
     
         8 . The mixture of  claim 2  wherein at least 70% of the glass particles have a size of 50 mesh or smaller. 
     
     
         9 . The mixture of  claim 8  wherein at least 95% of the glass particles have a size of 50 mesh or smaller. 
     
     
         10 . The mixture of  claim 1  wherein 5% or less of the glass particles have a size greater than 50 mesh. 
     
     
         11 . The mixture of  claim 10  wherein 10% or less of the glass particles have a size smaller than 300 mesh. 
     
     
         12 . The mixture of  claim 11  wherein at least 70% of the glass particles have a size of 50 mesh or smaller. 
     
     
         13 . The mixture of  claim 10  wherein at least 70% of the glass particles have a size of 50 mesh or smaller. 
     
     
         14 . The mixture of  claim 1  wherein at least 70% of the glass particles have a size of 50 mesh or smaller. 
     
     
         15 . The mixture of  claim 14  wherein 10% or less of the glass particles have a size smaller than 300 mesh. 
     
     
         16 . The mixture of  claim 14  wherein at least 95% of the glass particles have a size of 50 mesh or smaller. 
     
     
         17 . The mixture of  claim 16  wherein 5% or less of the glass particles have a size greater than 50 mesh. 
     
     
         18 . The mixture of  claim 17  wherein 45% to 50% of the glass particles have a size greater than 100 mesh. 
     
     
         19 . The mixture of  claim 18  wherein 10% or less of the glass particles have a size smaller than 300 mesh. 
     
     
         20 . The mixture of  claim 1  wherein 10% or less of the glass particles have a size smaller than 300 mesh.
