The raw autoclaved aerated concrete waste (RA) is an important construction and demolition waste. The present work investigated the possibility of utilizing ultrafine autoclaved aerated concrete waste (WA) as a supplementary cementitious material (SCM) after wet-milling disposal. Results indicated that it is possible to realize the utilization of RA as a SCM by wet-milling treatment. The ultrafine WA blended mixture presented earlier hydration heat flow than the other alternatives. WA blended mixture showed almost the highest reactivity index (almost 100%) and compressive strength at each curing age, whereas coarse RA and SS blended systems presented the lowest values. WA blended mixture showed relatively low initial and secondary sorptivity coefficients. It was concluded that the high secondary sorptivity coefficients of FA and RA was due to the formation of connected voids by porous RA particles and partially reacted hollow FA spheres.

高压灭菌的加气混凝土废料（RA）是重要的建筑和拆除废物。本工作研究了湿磨处理后利用超细高压灭菌加气混凝土废料（WA）作为补充胶凝材料（SCM）的可能性。结果表明通过湿磨处理可以实现将RA用作SCM。与其他替代品相比，超细WA共混混合物的水化热流更早。WA混合混合物在每个固化龄期都显示出几乎最高的反应活性指数（几乎100％）和抗压强度，而粗糙的RA和SS混合体系显示出最低的值。WA共混混合物显示出较低的初始和次级吸着系数。
