High-strength concrete has a low water-binder ratio and a large amount of cementitious materials, which leads to an increase in hydration temperature, so plastic shrinkage and self-shrinkage. Although high-strength concrete has a higher tensile strength, it has a high elastic modulus, which will cause higher tensile stress under the same ...
