CHARACTERIZATION OF PORTLAND CEMENT PASTE USING MIP, NANOINDENTATION AND ESEM TECHNIQUES

Abstract eng:
The performance of concrete is increasingly designed through durability. Durable concrete is a driving force for a sustainable production and use of cement. One way to achieve durability of concrete is to fathom the mechanical properties of the cement matrix and the main associated features of its microstructure. Non-destructive experimental methods such as nanoindentation and ESEM were used to characterize the hardened Portland cement paste with w/c=0.40 hydrated at 7, 14 and 28 days. Grid indentation analysis was employed between approximately two equal sized hydrated cement particles. Additionally, MIP was used as a generally accepted technique for deriving porosity and pore size distribution and results correlated to those received from ESEM image analysis.
