000003039 520__ $$2eng$$aExperimental work has been carried out in order to describe the influence of hot mixing on the properties of hardened mortars in comparison with mortars made of lime hydrate and lime putty. Lime from the same quarry and producer was used in the form of lime hydrate, lime putty and quicklime. Two types of quicklime were used varying in their calcination conditions and also their reactivity. Standard specimens 40 x 40 x 160 mm were cast and evaluated after curing. Mechanical (compressive and flexural strength) and physical properties (open porosity, bulk density and capillary absorption) were determined on the specimens of hardened mortars. Thin sections of the mortars were prepared and evaluated under polarising microscope in order to describe the structure of mortar including also the presence of binder related particles. The hot mixed mortars produced had comparable hardened properties with the lime putty and lime hydrate mortars. Due to the micro-cracks in the binding matrix the hot mixed mortars showed higher porosity and capillary absorption. The heterogeneity of the hot mixed mortars was a result of the preparation technology.
