【摘要】 作为燃煤灰渣之一的循环流化床灰,成分比煤粉炉粉煤灰更加特殊和复杂,综合利用程度低。当将其作为水泥混凝土用辅助胶凝材料时,明显增加水泥基胶凝材料的标准稠度用水量,降低胶砂流动度。相对于普通塑性混凝土,循环流化床灰更适用于碾压混凝土这种干硬性混凝土体系。更多还原

【Abstract】 Circulating fluidized bed ash, a kind of coal ashes, is less utilized for its special and complex components. When used as supplementary cementious material, it can obviously enhance the standard consistency water volume of cement based materials and reduce the mortar fluidity as well.Compared with ordinary plastic concrete, circulating fluidized bed ash is more suitable for hard concrete system like roller compacted concrete.更多还原
