Mechanical and Durability Performance of Self-Compacting Concrete Incorporating Supplementary Cementitious Materials

Self-Compacting Concrete (SCC) is a high-performance concrete capable of flowing under its own weight without external vibration. This study evaluates the mechanical and durability performance of SCC incorporating supplementary cementitious materials. Mechanical properties were assessed through compressive strength and split tensile strength tests at 7, 28, and 56 days. Durability characteristics were evaluated using Rapid Chloride Penetration Test (RCPT), sorptivity, water absorption, and acid attack resistance. Experimental results indicate that SCC exhibits superior mechanical strength and enhanced durability compared to conventional concrete. Reduced permeability, lower capillary absorption, and improved resistance to aggressive environments confirm the suitability of SCC for long-life infrastructure applications.
