A(3) The additives (
Con modern terminology, the additive is per material “added in small quantities onesto per liquid or granular material sicuro produce some desired modification to its characteristics” (ISO 6707–1:2020), while the admixture is verso material “added in small quantities before or during a missaggio process mediante order sicuro modify the characteristics of per mixture”. However, the difference between the two terms lies mainly sopra that the additive is added during the manufacturing of the cement, while the admixture is added esatto the concrete during missaggio. Moreover, the Adouci EN 934–2 canone states that the admixture for concrete should be mediante an amount not greater than 5% by mass, compared with the cement. Therefore, under the current rules, the additif of materials, such as ground ceramic fragments, per considerable proportions would fall into the category of aggregates and not that of additives.
However, one of the main aims of the archaeometric study on ancient mortars and plasters is onesto reconstruct the production’s phases and the supply modalities of each component.
