Method for producing Portland cement clinker by using high-content crystalline SiO2 siliceous raw material
The invention discloses a method for producing Portland cement clinker by using a high-content crystalline SiO2 siliceous raw material, which comprises the following steps: doping a chemical activator into the high-content crystalline SiO2 siliceous raw material, grinding to improve the reaction activity of crystalline silicon in the siliceous raw material, preparing a Portland cement raw material by using the high-content crystalline SiO2 siliceous raw material as a raw material, and calcining to obtain the Portland cement clinker. The clinker prepared by the method has the characteristics of high early strength and high later strength, the early strength and the later strength of the clinker are developed in a matched manner, the strength of cement mortar prepared from the clinker reaches 30 MPa, 45 MPa and 60 MPa or above in 3 days, 7 days and 28 days respectively, and the mechanical property of the clinker is obviously improved.
本发明公开了一种采用高含量结晶SiO2硅质原料生产硅酸盐水泥熟料的方法，在高含量结晶SiO2硅质原料中掺入化学激发剂进行粉磨，以提高硅质原料中结晶硅的反应活性，然后将其作为原料配制硅酸盐水泥生料，经煅烧得到硅酸盐水泥熟料。采用本发明方法制得的熟料有高早强、高后期强度的特点，熟料的早期强度和后期强度匹配发展，由该熟料制备的水泥砂浆强度3天、7天、28天分别达到30MPa、45MPa、60MPa以上，熟料力学性能提升明显。
