Evaluating self-healing efficiency in cementitious materials

Friday, 6 March 2015

During the last decade, self-healing of concrete has attracted so much attention in the research community as a promising tool toward more durable and sustainable infrastructures.

Although various self-healing approaches have been vastly studied, employment of different assessment methods in these studies has made it difficult to compare the efficiency of various self-healing mechanisms.

Four robustness criteria for evaluating self-healing efficiency are proposed

A paper conducted by Australian researchers presents a review of test methods which have been commonly utilised to assess the efficiency of self-healing mechanisms in concrete. Three broad categories of assessment methods are considered, namely visualisation and determination, assessment of regained resistance and assessment of regained mechanical properties. Moreover, as a pathway toward standardised evaluation of self-healing mechanisms, various assessment techniques are evaluated against four proposed essential criteria – reliability, quality of results, operational considerations and in-situ applicability.

The study is published in: Construction and Building Materials, Volume 81, 15 April 2015, Pages 233-247.
