Zusammenfassung: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.
