Five marble dust powder (MDP) substitution percentages (i.e. 0%, 10%, 20%, 30%, and …
Marble powder as an adsorbent. As the main constituent of WMP is dolomite, principally calcium and magnesium carbonates, the positively charged Ca + and Mg + ions present in dolomite possess an affinity toward negative ions. They hence can be employed as an adsorbent for anionic adsorbates (Mehta et al. 2016).Table 2 presents …
The need to reach carbon neutrality as soon as possible has made the use of recycled materials widespread. However, the treatment of artificial marble waste powder (AMWP) containing unsaturated polyester is a very challenging task. This task can be accomplished by converting AMWP into new plastic composites. Such conversion is a …
