ABSTRACT:
A method for fabricating structural building blocks having a cured binding material dispersed within block forming media thereof comprises a plurality of operations. An operation is performed for depositing a volume of block-forming media within a media receiving cavity of block forming equipment. The block-forming media includes a curable binding material dispersed therein and curing of the curable binding material is caused by contact with a prescribed activation material. After or in conjunction with depositing the volume of block-forming media, an operation is performed for depositing the prescribed activation material into the media receiving cavity. Such depositing of the prescribed activation material causing at least a portion of the prescribed activation material to be dispersed within the volume of the block-forming media. During depositing of the prescribed activation material or after depositing of the prescribed activation material is completed, an operation is performed for compressing the block-forming media within the media receiving cavity.
