摘　　要：根据传统水泥生产流程,本研究使用后掺法将建筑废弃烧结页岩砖粉末用作水泥混合材料生产生态水泥。首先对废弃烧结页岩砖粉末做XRD理化成分分析,得出其主要成分包括SiO_(2)、Al_(2)O_(3)、Fe_(2)O_(3),这些成分符合制备硅酸盐水泥的要求。按照规范要求做3 d、28 d硅酸盐水泥强度试验,所制备的生态水泥满足强度要求。研究结果表明,无论是采用单掺还是复合掺的制备方法,掺入废弃烧结页岩砖粉末制备出来的生态水泥都能够满足硅酸盐水泥相关规范的要求,可以在工业建筑中推广使用。According to the traditional cement production process,this subject uses the post mixing method to use the building waste sintered shale brick powder as cement mixture to produce ecological cement.Firstly,XRD physical and chemical composition analysis of waste sintered shale brick powder shows that its main components include SiO_(2)、Al_(2)O_(3)、Fe_(2)O_(3),which meet the requirements of preparing Portland cement.The strength test of Portland cement for 3 d and 28 d is carried out according to the specification requirements,and the prepared ecological cement meets the strength requirements.The results show that the ecological cement prepared by mixing waste sintered shale brick powder can meet the requirements of relevant specifications for the preparation of Portland cement,and can be popularized in industrial buildings.
