Effect of Marble Powder and Dolomite on the Mechanical

impact strength of the composite PVC/dolomite reaches the maximum value of 60.95 J/m when 10 phr of dolomite is introduced. While the maximum impact strength of the PVC/marble is 58.77 J/m when 5 phr of marble is introduced. This result suggests that the dolomite has an ef fect of hardening on the PVC better than that of the marble.

Textural controls on the brittle strength of dolomite

Continued experimentation, and numerical analysis, on physically diverse samples will enable a better understanding of the relationship between grain size, porosity, and texture and the initial flaw length, and consequently the impact of these parameters, along with confining pressure, on the ultimate strength of dolomite.

Impact of the Geometrical Parameters of Dolomite

The influence of grain shape on the material strength, porosity, and hydration gaps was determined. Debonded porosity, as a result of aggregate impurities, was shown using computer tomography analysis. It was shown that the arrangement and shape of the grains has a significant impact on the performance properties of hardened preplaced concrete.
