Self Healing Concrete

Self Healing Materials is a new research area that gets a lot of attention in recent years. Self Healing Concrete is a term that is used for cement-based materials that repair themselves after the material or structure gets damaged due to some sort of deterioration mechanism.

In this blog we will update you on the progress of the Self Healing Concrete projects running in the section Materials & Environment and the Microlab of the faculty of Civil Engineering and Geosciences of Delft University.

This blog contains a description of the running projects that are financed by AgentschapNL, DCMat, STW and industrial partners. Also a page "Literature & Videos" is included where a lot of publications can be found.

Self Healing Concrete Workshop 17-May-2011

This is not an announcement.... for that it is too late. But on May 17th 2011 we had a workshop on Self Healing Concrete that we organised for our sponsors (AgentschapNL, DCMat and STW) and our inductrial partners. Below you can find the program of the day. Maybe you missed it..... But the good thing is, that you can download all the presentation from this BLOG. Go to the 'Literature & Videos" page and you will find a link to the presentations at the bottom of this page.

The Workshop would not have been possible without a grant from DCMat.

Bacterial Concrete in the news in Japan.

We spotted this article with a photo of Henk Jonkers while testing a piece of Bacterial Concrete.
So probably the article is also about self healing of concrete with bacteria. However, we are not complete sure......

Self Healing Concrete in COBOUW

In a special issue "Beton in Beeld" of COBOUW (in Dutch) an interview with Erik Schlangen on the developments of Self Healing Concrete was published recently (June 2011). Below a copy of the article is shown. If you click on the image you get a somewhat bigger version and you might be able to read Dutch.

Stamps on "Bacterial Concrete"

Did you know that you can buy stamps with the Bacteria that we use in our Bacterial Concrete.

The Dutch Society of Microbiologists had their 100th anniversary and to cellebrate this Stamps of different species of Bacteria were given out. The Bacteria we put in our concrete are on one of the stamps.

Self Healing Asphalt

Did you know that we have a separate BLOG on Self Healing Asphalt?
On this page you can find all the info on the development of this material and the application in a Dutch Highway A58.

3rd Int. Self Healing Materials Conference, Bath, UK

End of June was the 3rd int. conf. on Self Healing Materials in Bath UK. Our group was represented by 9 people (2 faculty members, 4 Post Docs and 3 PhD students). Try to find them all in the picture below.

We had 1 keynote lecture (by Henk Jonkers), 5 regular presentations and 2 poster presentations. In total we had 10 articles in the proceedings. You can find the extended abstracts on the "Literature & Videos" page.

Major update of Blog...

This week we finaly did a major update of our Blog on Self Healing Concrete. The project descriptions are updated (although more info will follow in the coming weeks).
The "Literature & Videos" page is made up to date. You can find there a lot of publications by our group (some of them can be downloaded). Furthermore you can watch some interesting videos.
The page "Who is Who" had some new faces and you find all the e-mail addresses of all the self healers in our group.
