The need to reduce mixing water to the same degree of workability and fluidity is one of the major demands of the mortar market.
For this reason, plasticizers or water reducers are the ideal solution. If the quantity of water is reduced and additive is added (in low percentages), the same fluidity characteristics can be obtained and some problems, such as excessive bleeding, avoided at the same time.
Moreover, less mixing water means greater water/cement interaction, thus increasing the percentage of binding agent in the mixture and enhancing its structural features.
The addition of plasticizers, according to the various recipes, has an impact on the behaviour of the mortar without affecting its mechanical properties once it has hardened.
