Method for determining microscopic characteristics of concrete interface transition area

The invention provides a method for determining microscopic characteristics of a concrete interface transition area, which comprises the following steps of: randomly putting cement particles based on particle size distribution parameters of the cement particles to obtain particle sizes and position coordinates of the cement particles; according to the particle sizes and the position coordinates of the cement particles, obtaining the cement content and the local water-cement ratio of each slice by adopting a slice processing method; obtaining a porosity distribution curve according to the cement content and the local water cement ratio; and dividing the boundary of the interface transition area according to the porosity distribution curve, and determining the microscopic characteristics of the interface transition area. According to the method, all factors influencing the microscopic characteristics of the interface transition area are comprehensively considered, and a theoretical basis can be provided for imp
