Abstract


The microstructure of the material determines the macroscopic properties , roads, concrete is no exception , the internal pore structure of the different scales directly affect macro durability , thereby affecting the life of the cement pavement . Therefore, in-depth study the roadway concrete structure and macroscopic properties of traits of road concrete understanding on the essence and law to guide the composition of the design is of great significance . Selected different scale levels typical pore structure and pore structure and morphology as the object of study , a comprehensive and systematic analysis of the three with the macro Road summarized the material composition of the microstructure with the relationship between the performance the impact of the law , and thus recommended mix design parameters based on the microscopic structure of a reasonable range . The basis of theoretical analysis , developed a the hole measurement method based on digital image processing technology , first introduced in the pore structure of the total porosity , average pore size , and other indicators, stomatal test and evaluation system of the system than the traditional stomatal test method is simple , fast , and high accuracy . Meanwhile, across different structural levels for the first time , a comprehensive and systematic analysis of the impact of the variation of the pore structure of the different scales of the road concrete road performance , and recommended to meet the different durability partition chloride ion impermeability , anti- range of the of frozen requirements reasonable stomatal parameters and the hole gradation . The theory of this research has a clear and complete system the advanced practicality , has an important role in guiding the design and testing of cement concrete pavement .
