A Comparative Study of the Mechanical Behavior of Normal-Strength and High-Strength Concrete

CODEN: ACEMF9

Abstract

A test program was carried out to examine the relative behavior of normal-strength concrete (NSC) and high-strength concrete (HSC). The experimental program included macroscopic and microscopic study of NSC and HSC specimens (designed compressive strengths of 27.6 MPa and 82.8 MPa at 28 days). The macro-behavior of concrete was determined on the basis of multi-axial testing, while the micro-behavior was evaluated using acoustic emission (AE) test and optical petrographic microscopic analysis. The results reveal that, for both NSC and HSC, macro-responses are dependent on and a manifestation of various micromechanical changes. The normal-strength concrete yielded a very different behavior in changes of internal microstructure as compared to the high-strength concrete.
