利用两种类型建筑垃圾(废混凝土、废砖)制备了两种可用于水泥、混凝土的再生超细微粉,对其颗粒形貌、粒径分布、化学成分和胶凝活性等性能进行测试,并与矿粉、粉煤灰的特性进行比较。结果表明：建筑垃圾再生超细微粉颗粒多为不规则形状,比表面积为600 m2/kg以上；化学成分中氧化硅、氧化钙含量较高,氧化铝含量较低；其早期活性与矿渣粉相当,28 d活性与普通粉煤灰持平。

Prepare two kinds of recycled ultrafine powder by concrete and brick from construction waste, take experimen-tal research on their properties, results show that: the particle shape of recycled ultrafine powder are irregular, and their spe-cific surface area are higher than 600 m2/kg. The content of SiO2 and CaO are relative high, and the content of Al2 O3 is rela-tive low. Their early activity are close to slag, and their 28d ac-tivity are close to fly ash.
