Sažetak
The micro-porous structure of slag high performance concrete (SHPC) imposes great influence on its permeability and durability. Based on air permeability experiment and mercury injection experiment, the author analyses the correlation between SHPC pore structure and air permeability by taking parameters of SHPC air permeability and pore structure as random variables, finding the mechanism and level of influence of various mix proportions of SHPC pore structure parameters on air permeability. Research and analysis show that median pore diameter and threshold diameter of SHPC are certainly correlated to air permeability and can be used to represent SHPC air permeability, while other parameters are not closely correlated to it and cannot represent SHPC air permeability directly by single one.
