This monograph is written based on the author's extensive research over the last decade on the assessment and control of cracking of early-age concrete. The technique of crack control of modern concrete at early age is further developed through experimental and theoretical research, such as mitigating the drop of IRH, controlling the hydration process, decreasing the shrinkage, and increasing the tensile strength. It indicates the innovative findings and establishes prediction models on early-age internal relative humidity, autogenous shrinkage, tensile creep of modern concrete considering water-to-cement ratio, curing temperature., etc; reveals the variation law and mechanism of early-age cracking resistance of modern concrete with different kinds of fibers, supplementary cementitious materials, chemical admixtures, and internal curing agents under circumferential or uniaxial restrained condition. It is designed as a reference work for professionals or practitioners and a textbook for undergraduates or postgraduates.
