    • Early strengthening type cement is provided to demould at an early stage by using existing normal portland cement production equipment. A particle size of the early strengthening type cement is graded by using the existing normal portland cement production equipment. The early strengthening type cement exhibiting excellent early strength performance is manufactured by mixing the early strengthening type cement consisting of particles less than the average diameter 10 mum and the normal portland cement. Early strengthening type cement includes the cement corpuscle of 10~60 weight% and normal portland cement of 40~90 weight% at the cyclone separator bag filter of the grinding process. The cyclone separator bag filter is used as the binding material for the early strengthening type cement. Or the early strengthening type cement comprises the cement corpuscle in which the particle size of the early strengthening type cement is graded, the limestone fine dust and normal portland cement. And the limestone fine dust has fineness and calcium carbonate content of the fixed range.
    • 早期强化型水泥通过使用现有的普通硅酸盐水泥生产设备在早期阶段提供给脱模剂。 早期强化型水泥的粒度通过使用现有的普通波特兰水泥生产设备进行分级。 通过混合由小于平均直径10um的颗粒和正常波特兰水泥组成的早期强化型水泥,制造出具有优异的早强度性能的早期强化型水泥。 早期强化型水泥包括10〜60重量%的水泥颗粒和40〜90重量%的正常波特兰水泥在旋风分离器袋式过滤器的研磨过程中。 旋风分离器袋式过滤器用作早期强化型水泥的粘合材料。 或早期强化型水泥包括早期强化型水泥粒度分级的水泥颗粒,石灰石细粉尘和普通硅酸盐水泥。 而石灰石细粉尘的细度和碳酸钙含量固定在一定范围内。
