摘要(Abstract)：

采用4种不同尺寸的石墨烯（PG1、PG2、PG3、PG4）制备石墨烯水泥基材料，并研究石墨烯尺寸对水泥基材料水化性能、力学性能的影响。试验结果表明：石墨烯的掺入提高了水泥的水化速度，降低了水泥浆体的流动性，其中小尺寸的石墨烯效果最为明显；小尺寸石墨烯有助于增强抗压强度，大尺寸石墨烯有利于提高抗折强度。通过X射线衍射仪（X-ray diffractometer, XRD）及扫描电子显微镜（scanning electron microscope, SEM）等设备分析可知，掺入4种石墨烯均未改变水泥水化产物的种类，但能够有效细化水化产物氢氧化钙（calcium hydroxide, CH）晶体的尺寸，提高水泥基体的密实度，石墨烯尺寸越小，对CH晶体的细化效果越明显。
