Abstract

High-performance concrete is a specialized type of concrete renowned for its exceptional strength, durability, and resilience to various environmental stresses. Typically it’s crafted using a combination of two or three supplementary cementitious materials (SCMs) in precise proportions to achieve specific performance attributes. Ternary blended concrete, for instance, incorporates three different SCMs alongside Portland cement. This study delved into the relationship between mechanical and durability aspects of high-performance concrete. Durability measures including electrical resistivity, water absorption, porosity, chloride penetration, and carbonation were analyzed alongside the compressive strength of various concrete mixes. The findings indicate that ternary blended concrete displays superior electrical resistivity, lower water absorption, reduced critical pore size, decreased chloride diffusion coefficient, and slower corrosion rate compared to binary mixes. Power correlations were conducted on these durability parameters, revealing a positive correlation between compressive strength and durability properties.
