Study on Concrete Materials and Durability in Port Engineering
This research was focused on the application potential of Self-Compacting Concrete(SCC)in port engineering,especially regarding its material and structural durability in areas difficult for manual compaction.A suite of experimental tests was employed,including assessments of compressive strength,flexural strength,chemical durability(such as sulfate erosion and chloride ion penetration),as well as microstructural analysis using Scanning Electron Microscopy and X-Ray Diffraction.Additionally,the performance of SCC under various environmental conditions was further evaluated through environmental simulation tests and time-series analysis.The results indicated that SCC demonstrated a lower erosion rate in chemical durability tests compared to traditional concrete grades C20 and C30,highlighting its superior resistance to chemical attacks.Microstructural analysis uncovered SCC's dense and uniform microstructure,enhancing its crack resistance and durability.In environmental simulation tests,SCC exhibited higher performance stability across different temperature conditions,particularly excelling in long-term performance maintenance compared to C20 and C30.The superior performance of SCC positions made it as an ideal material for enhancing the reliability and reducing maintenance costs of hydraulic engineering structures.
