摘　　要：在“双碳”背景下,水泥行业面临着严峻的减排压力,而水泥的环境影响和性能通常呈正相关关系。为了探究低环境影响高性能的水泥制备方法,运用了生命周期评价方法对水泥生产全过程的环境影响进行了量化,并基于环境评价结果,引入DOE技术分析了熟料煅烧阶段不同工艺参数组合对二氧化碳排放量和熟料抗压强度的影响。结果表明:石灰石配比和煅烧温度显著影响煅烧阶段的二氧化碳排放量,石灰石配比、生料细度和回转窑转速显著影响熟料抗压强度。此外,利用响应优化,得出了以二氧化碳排放量最小化,28 d抗压强度最大化为目标时,最佳因子水平组合为石灰石配比取70%,生料筛余取12%,煅烧温度取1300℃,回转窑转速取6 r/min,此时二氧化碳排放量为817.18 kg/t,28 d抗压强度为50.40 MPa。研究结果可为水泥环境影响和性能的综合优化研究提供参考。Cement industry is facing severe pressure of the emission reduction in the context of the“dual carbon”target.Yet,the environmental impact caused by cement production is often positively related to the performance of cement.In order to explore the method of cement production with low environmental impact and high performance,Life Cycle Assessment(LCA)was used to quantify the environmental impact of the whole cement production process.Based on the environmental assessment results,DOE technology was introduced to analyze the influence of different process parameters combination on CO2 emission and compressive strength during the stage of clinker calcination.The results indicate that the CO2 emission is significantly influenced by the limestone ratio and the calcination temperature.And the limestone ratio,the raw meal fineness and the rotary kiln speed significantly affect the compressive strength of the clinker.In addition,utilizing the response optimization,the optimum combination of factors for minimizing CO2 emission and maximizing 28 d compressive strength was found to be 70%for the limestone ratio,12%for the raw meal fineness,1300℃for the calcination temperature and 6 r/min for the rotary kiln speed,which resulted in the CO2 emission of 817.187 kg/t.cl and 28 d compressive strength of 50.40 MPa.The research results can provide reference for the research on the comprehensive optimization for the environmental impact and performance of cement.
