Abstract
<p>A New low-carbon concrete binder consisting of recycled cementitious powder produced from fresh ready-mixed concrete waste is focused. Dehydrated sludge powder (DPS) is utilized as supplemental cementitious material in combination with Portland cement. This study introduces quality controlling scheme by adopting apparent specific surface area in DPS, which clearly indicates quality of DSP in terms of such as strength contribution after hardened. Experimental findings to reveal article size distribution, remaining unhydrated cement amount, and corresponding compressive strength development demonstrated that apparent specific surface area clearly illustrates quality of DSP with solid physical background.</p>
