Concrete Formulation Study for Informal and Semi

If the formulation of a concrete can be understood as the process of selection of constituents (aggregates, cement, additives) and their proportions optimal to manufacture a complex possessing certain required properties (consistency, resistance, durability...), it is nonetheless true to note that this is still done for the most part empirically, whereas there are more rational scientists [3] .
