Impact load-induced microstructural damage of concrete ...

Understanding the correlation between the mix proportions, micro structural characteristics, and macro-scale properties of concrete (i.e. the process-structure-properties relationship) is fundamental to achieving a more advanced understanding of how to apply and optimise this abundant engineering material. Although, concrete has been traditionally evaluated by its physico-mechanical and ...

Feb 01, 2012  Typical images captured to investigate micro-structural damage are presented in Fig. 13, Fig. 14 for the lightweight concrete and conventional concrete, respectively. The concentrations of the micro-cracks in the ITZ could be an important parameter to help understand the failure process of the specimens subjected to impact loading.

Recycled aggregate concrete (RAC) is a type of multiphase porous material. Its aggregate, admixture, and environment have a crucial impact on its pore structure. Nuclear magnetic resonance (NMR), a nondestructive testing method, was adopted to demonstrate the process of air-entrained recycled coarse aggregate concrete (ARAC) and non-ARAC microstructural damage in a freeze–thaw environment.

EVALUATION OF LINEAR AND NONLINEAR VIBRATION

A common example is estimating in-situ concrete strength when the structural capacity of a concrete member is required to be evaluated. This need is encountered in day to day structural evaluations and structural forensics. Monitoring early-age compressive strength of concrete also is often required during the construction of a building.
