This monograph is written based on the author's research on the assessment， control， and repair of cracking of early-age concrete in the recent decade. The technique of internal curing for increasing cracking resistance of early-age concrete is further developed through experimental and theoretical research. It establishes models for predicting the internal relative humidity and autogenous shrinkage of internally cured concrete at early age; reveals the variation law and mechanism of early-age tensile creep of internally cured concrete; and explores the variation law and mechanism of early-age cracking resistance of internally cured concrete under continuous restrained condition or uniaxial restrained condition.lt is designed as a reference work for professionals or practitioners and a textbook for undergraduates or postgraduates. As such， this book provides valuable knowledge， useful methods， and practical experience that can be considered in the field of concrete cracking control.
