Both to optimize the dosing time and fit the mixer equipment condition (Dosage Center with four compartments), four aggregates were selected to the manufacturing process: gravel, crushed stone, garnet stone and sand powder. Aggregating as well as having a cost lower than cement does, gives the concrete a greater stability and durability [ 23, 24 ].

Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed …
