Anti-crack mechanism of concrete shrinkage compensation

Based on a large number of experiments, a dynamic control theory and method for concrete shrinkage compensation are proposed for research of the effect and safety of the concrete shrinkage compensation technique. The addition of a certain amount of VF anti crack additive in concrete can make the concrete expansion curve approximately agree with the concrete shrinkage curve, ensuring that the concrete can meet the requirement for its tensile strength during the process of its volume deformation, thus, the cracking of concrete can be effectively controlled.
