Resumen

The use of plasticizing admixtures in order to improve the handling of cement-based media has been extensively reported. High-range water reducers or superplasticizers (SPs) act reducing the water demand and enhancing the flowability of the fresh mortars, yielding workable materials. So far little attention has been devoted to the study of the performance of superplasticizers in lime-bearing pastes and mortars. The widespread use of hydrated lime and pozzolan-hydrated lime pastes for paints, consolidant products, soil treatments and the obtaining of repair mortars and grouts, especially for architectural monuments of the Cultural Heritage, supports the interest of these materials. In order to design suitable hydrated lime pastes and mortars, the use of compatible and effective SPs seems to be imperative.
