Definition:
A substance that is added to a material to enhance or modify its characteristics,
such as curing time, plasticity, colour, or volatility. Additives were
used for the preparation of stucco marble. The aim of inorganic additives
is to increase hardness, resistance, and durability and to retard setting.
They are added at some stage of the working process. The aim of adding
organic substances is either to improve the workability, to harden the
mass, to retard setting, or to influence the mechanical properties of the
stucco mass in a way that it can be polished so that a sufficient gloss
is obtained. |

o acquistino particolari proprietà. |
