An experimental study on quaternary lime pozzolana based mortar

Discover Civil Engineering
Abstract Lime mortar is the traditional construction material mostly used before 20th century as a primary binding material. In this study the performance of hydrate lime mortar is studied by addition of pozzolana materials such as micro silica, fly ash and metakaolin.

Competition between Hydration and Carbonation in Hydraulic Lime and Lime-Pozzolana Mortars

, 2010
A combined reaction of hydration and carbonation takes place in hydraulic lime and lime-pozzolana mortars. Hydration reactions are the first reaction and carbonation of lime is the complementary reaction in the strength gain.
