چکیده انگلیسی
In this study, the feasibility of improving the durability of Ultra-High Performance Concrete (UHPC) by incorporating calcined Layered Double Hydroxides (C-LDHs) was investigated. The spread flow, air content, permeable porosity, compressive strength, and durability of the designed UHPC were evaluated. Furthermore, the influence of C-LDHs on cement hydration and microstructure of the designed UHPC were studied. Experimental results indicated the incorporation of 1% C-LDHs improved durability of UHPC in chloride and sulfate environment, with compressive strength enhanced simultaneously. The chloride binding capacity of C-LDHs is far better than that of cement, fly ash and silica fume, reaching a chloride absorbance of 3.28â¯mg/g. Therefore, C-LDHs is a functional anions absorbent materials in UHPC system, which is promising in the currently critical components of offshore buildings and structures.
