dolomitic and volcanic. The presence of volcanic sediment makes dolomite more resistant to weathering and endows it with hardness [14–16]. However, it was found that the use of dolomite in its raw form could not improve the mechanical properties of the polymeric matrices. This is because dolomite particles easily agglomerate, while their ...
The results of adding dolomite as a co-filler in enhancing the physical and mechanical properties of the polymer composite are quite impressive, where it can improve certain polymer properties that may not be achievable if only a single filler is used, properties such as hardness, impact strength, thermal stability, and flame-retardancy.
Hence, dolomite can be used as filler in adjusting pore-structure [33]. Moreover, the calcined dolomite is an effective adsorbent for the removal of Cu 2+, Pb 2+ [34], Sr 2+ and Ba 2+ [35], which shows great potential for wastewater treatment. In addition, Azimi et al. [36] synthesized dolomite-containing geopolymer with improved …
