摘要
湿度是影响混凝土收缩的重要因素之一。本文通过对大量试件的测试表明,湿度对自密实混凝土的早期收缩具有显著影响,有效确保其湿度在适当范围内,能有效控制自密实混凝土早期收缩。
Humidity is an important factor that affects shrinkage of SCC(short for self-compacting concrete).In this paper the results indicate that early-age shrinkage of SCC is affected abviously by relative humidity.Keeping relative humidity unvariable or varying little is an effective way to control early-age shrinkage of SCC.
