My secondment in IFSTTAR-Nantes

Because I am in the European project 'INFRASTAR'. Each ESR should leave their host-labo and go to another country/city to work with the other ESRs. This is the so called 'Secondment'.

So, I started my secondment and came to Nantes in April to work with ESR2 Antoine. Antoine works on fiber optics, and I work on ultrasonic sensors (CODA wave). So we will examine the complementarity of our two technologies by doing test on metric slab test.

1:  We install fiber optics and ultrasonic sensors to rebars:
2:We put the rebars into the formworks and wait for the concrete. 3: Preparation of concrete 
4: Concrete pouring
Then we need to wait for 28 days.

Who am I? Where do I come from? And what am I doing?

Hey. Everyone, welcome to my blog.I will introduce u myself and give you a quick view of my PhD topic.

Who am I? Where do I come from?
My name is Xin WANG. It is a typical Chinese name, and yes. I am from China. For the first year of my undergraduate, I studied underwater acoustics in China. Then I moved to France. I studied acoustics as an undergraduate in Université du Maine. Then, for my master, I changed my major to electronics and continued my study in Pierre and Marie Curie University.   Now I am working in a European project named  'INFRASTAR' and doing my PhD thesis in BAM (Bundesanstalt für Materialforschung und -prüfung), Berlin.
What am I doing? My PhD topic is 'Advanced ultrasonic instrumentation for interferometric monitoring'. So what I do is to monitor the concrete using ultrasonic sensors. But why we do this? Concrete is the single most widely used material in the world especially for the civil infrastructures. The neglecting and excessive use of the e…
