镁渣替代石灰石配料烧制硅酸盐水泥熟料

Substituting magnesium slag for limestone to produce Portland cement clinker

实验证明,镁渣可改善生料的易烧性;在镁渣参与配料的生料中,掺加HBZ或HPZ后,促进了fCaO的吸收,能大幅度改善生料易烧性。在同时掺有1.0%HBZ和1.5%HPZ时,熟料3d和28d抗压强度比空白样分别提高38.3%和12.2%;用镁渣替代20%石灰石烧成的硅酸盐水泥熟料3d和28d强度分别可以达到40.8MPa和65.2MPa。

From real practice, magnesium slag can improve burnability of raw meal. In raw meal proportioning with magnesium slag, adding of HBZ or HPZ can accelerate absorption of free CaO and modify raw meal burnability in great extent. When adding 1.0% of HBZ and 1.5% of HPZ simultaneously. 3d and 28d compression strength of clinker will raise 38.3% and 12.2% separately compared with those samples nothing added in. In case using magnesium slag replace 20% of limestone to produce Portland cement clinker, their 3d and 28d compression strength can reach 40.8 MPa and 65.2 MPa separately.
