Roof tile with an improved composition and method of making the same

A method for manufacturing a cementitious roofing tile, the method comprising:

• measuring a predetermined amount by weight percentage of dry components, the dry components including, a fine aggregate sand, an aggregate, a crushed glass and an alkali-silica reaction (ASR) suppressant;
• mechanically blending the dry components to form a homogenous dry composition mixture;
• adding a predetermined volume of water to the homogeneous dry composition mixture;
• forming a damp mixture;
• placing the damp mixture in a predetermined sized molding frame, the molding frame having a removable base plate;
• applying a compactive and vibratory force to the damp mixture within the molding frame to achieve a desired finished shape of a compacted tile;
• removing the compacted tile from the molding frame;
• and
• transporting the compacted tile to a controlled environment for curing until a desired strength associated with the compacted tile has been established for safe handling and transportation to construction sites;
• wherein the aggregate is selected from one of perlite, vermiculite, hemp, expanded clay, coco coir, shale and slate.
