Anotācija The local mineral deposits – clay and dolomite are widely used for production of building materials in Latvia. Investigations of new materials and energy saving methods are today`s topicality. One of the possibilities is to reduce production expenses using lower firing temperature, and, in addition, providing desired strength characteristics required for building applications ( Lindina et.al., 2011). For obtaining new materials the deformation and strength properties have to be analysed and taken into account. It is known, that a great part of architectural monuments in Latvia were built using low-temperature natural cement – dolomitic Roman cement as a binder and now it is time to start their restoration. As the production of dolomitic Roman cement stopped 60 years ago, it is urgent to develop a method on how to obtain low temperature binder from dolomite and clay similar to the historic type, from natural dolomitic marl produced Roman cement. At first, the composition as well as physical properties of hydraulic binders were investigated (Barbane et.al, 2012). In order to study the mechanical properties, a range of uniaxial loading tests with samples were performed using the testing equipment “Instron 5985”. For comparison ready-mixed calcitic Roman cement „Prompt” samples were previously tested. Analysis of the results shows stable mechanical property values. The resulting binder’s mechanical parameters could be used for further improvement of the historic building restoration works.
