Its properties are governed by the physical properties of the materials of which it is composed of and the manner in which they are bonded to each other Rock Mass • The insitu medium which comprises intact rock blocks separated by discontinuities. Rock masses are generally discontinuous and often have heterogeneous and anisotropic properties.
The results were as follows: The flame front speed and sinter coefficient decreased with an increase in MgO content from to % by adding dolomite. With an increase in MgO content from to %, the flame front speed, sintering utilization factor, and the value of RI decreased, while RDI and the softening–melting properties improved.
The suitability of Oreke dolomite in Kwara State, Nigeria as a raw material for the manufacturing of refractories was investigated. The Oreke dolomite samples were mingled with feldspar, clay, and quartz to form a blend. The fifteen (15) Blend samples were moulded and analyzed for their chemical, physical and mechanical properties.
Influence of Dolomite on the Mechanical Properties of Boiler Ash Geopolymer Paste By Y. Zarina, H. Kamarudin, A. M. Mustafa, Al Bakri, I. Khairul Nizar and A. R. Rafiza Abstract
The main modelling objective was to investigate the dependence of mechanical properties of dolomite ceramics on the mechanical properties and volume proportions of its components – clay and dolomite, assuming the composite structure of dolomite ceramics.

AGU Physical Properties of Earth Materials Dr. Kronenberg's expertise spans topics in structural geology, tectonophysics, and mineral physics with emphasis on the mechanical properties of Earth materials and the deformation mechanisms that govern rheology.
Consequently, the authors found that, as shown in Figure 7, the MOS cement produced by lightburned dolomite with a calcination time of 0·5 h at a calcination temperature of 850°C presented the best mechanical properties. The reason for this was that magnesite decomposed more completely in these conditions than with a shorter calcination time or at a lower calcination temperature.
