Strategic Behavior and Environmental Qualityes for which the binder (cement/FA) was replaced with 40% wt. QD was evaluated using two different tests: (a) Expansion tests to assess the durability of these dolomite-based, Mg-rich mixtures - as brucite (Mg(OH).) may be formed according to Eq. (.) (known as the ‘alkali-carbonate reaction’) and hence induce volume increase and expansion.
