We are proud to announce that we also created a BLOG for Self Healing Concrete.

Article in NRC 30/31 July
Another article discussing our project was recently published in NRC Handelsblad on July 30/31.
2nd edition of Self Healing Materials brochure
AgentschapNL published a new version of the Self Healing Materials booklet. You can download it by clicking on the image. Happy reading!
test results look promising....
Of course you are all waiting to see some results of the laboratory tests that are now being performed on the samples that we took from the road. We do not have final conclusions yet, however, tests show that the service life of the material might increase (a lot).
The results shown below are from the 4-point bending fatigue tests performed in the road engineering lab at Delft Univerity. In this set-up different type of tests are compared.
The first line in the graph at the right is for the reduction in flexural sifttness in the original fatigue test. The next line is if we repeat the fatigue test after a rest period of 18 hours. The third line is for the case if we apply heating to 70 C during the rest period. The heating realy improves the behaviour of the material
In the figure at the right it can be seen that we did do multiple loading cycles where we had rest periods including heating. The material almost recovers completely after each cycle and the total fatigue loading cycles that can be done is much much larger than the test without resting and heating.
Please don't get too exited....We should not conclude yet from this result that the service life of the road will increase in the same manner, however, it looks promissing, doesn't it?

article on project in Nederlands Dagblad
On August 4 the Nederlands Dagblad published an article in Dutch with the title
"The ideal asphalt does not exist yet" (but we are getting close....).

Self Healing Conference Bath
End of June we had a very interesting conference in Bath UK about self healing materials.
A lot of new research was presented and many good ideas for furthure work were proposed.
Below you see all the participants:
Erik presented the work on the self healing road. It turned out that this was one of the first real application (and maybe the only one...) of a civil engineering self healing material.
