Hardening accelerator additive: Additive that increases the speed of initial strength development of the concrete, with or without modification of the setting time.

Setting retarding additive: Additive that increases the time of the beginning of transition of the mixture to go from the plastic state to the rigid state.

Water-repellent mass additive: Additive that reduces capillary absorption of hardened concrete.

Multifunctional additive: Additive that affects various properties of fresh and/or hardened concrete by acting on more than one of the main functions defined in the additives mentioned above.

There are another variety of products that, without being strictly additives and therefore without being classified as them, can be considered as such since they modify concrete properties, as occurs with colorants or pigments that act on the concrete color, gas generators that do so on the density, etc.

Air-entraining additive: Additive that allows a certain amount of air bubbles to be incorporated during mixing, uniformly distributed, which remain after hardening.

Setting accelerator additive/accelerator for cement: Additive that reduces the transition time of the mixture to go from the plastic to the rigid state.
