摘　　要：研究了不同粒径的石英砂、憎水剂及养护环境对氧化铁黑着色混凝土的色相影响。结果表明,石英砂粗骨料比细骨料更有助于提高颜料的分散水平,从而提高着色强度,憎水剂的添加会降低着色强度,高湿的养护环境有利于得到高着色强度。The influences of different partical size of quartz sand,water repellent and maintenance environment on the hue of iron oxide black colored concrete were researched.Results showed that compared with fine aggregate,coarse quartz sand aggregate was more helpful to increase pigment dispersibilty and the tinting strength.Adding of water repellent would reduce the tinting strength.The maintenance environment with higher humidity was beneficial to the preparation of higher tinting strength.
