geo polymer is formed. The aggregates’ mechanical properties are controlled for variables such as loss of abrasion (durability) and alkali solubility and absorption, via editing minor quantities of Calcium in the form of other cheap industrial by-products (controlling the volume of mineral Anortite). The product mimic mineral formation found in nature, such as Feldspar, constitutes over 50% of the Earth’s crust and is a major ingredient of quarry-produced aggregates. Technologically, the process is simple: comprising mixing of fly ash with liquid waste for a setting time predetermined by specific Job Mix Formula for formation of Calcium Alumina Silicate crystalline clusters. Once formed, the mixture is introduced into an off-the shelve Continue Flow/Batch Reactor (similar to one used in the community waste treatment plants) and after a predetermined time, defined by the JMF at the thermal equilibrium of Bowen Reaction series, stable Calcium Alumina Silicate Feldspar Aggregates are formed from the melt via a very simple and cost-effective process of dropping the melt over a high-speed rotating hedgehog cylinder, promoting the gravitational ejection of droplets (required round geometry for concrete and road base). Forming asphalt aggregates with required rectangular geometry (for interlocking) is achieved by dropping the very hot pellets on the inclinated metal surface – 28
