The invention discloses
alite-
belite-
calcium sulphoaluminate
cement clinker prepared from high-
silicon low-grade limestone and aluminum
solid waste and a method, and the mineral phase of the clinker comprises the following components in percentage by
mass: 30-50% of C3S, 30-50% of C2S, 10-30% of C4A3, 0-5% of C4AF, 0-5% of CaSO4 and
metal ion oxide. 20-50% of high-
silicon low-grade limestone is used for partially replacing a
calcium raw material and completely replacing a siliceous
raw material; the aluminum
solid waste completely replaces an aluminum
raw material and an iron raw material. The
alite-
belite-
calcium sulphoaluminate
cement clinker prepared by the method is high in
utilization rate of the low-grade limestone and the aluminum
solid waste, does not need to improve a traditional
Portland cement clinker production process, and is good in burnability, low in
sintering temperature, high in hardening speed, high in early strength and stable in later strength development compared with the latter. The problem of utilization of low-grade limestone and aluminum solid waste is effectively solved, the
cement clinker production cost is reduced, and carbon emission in the cement production process is reduced.
