Can someone direct me to an image of the molecular structure of concrete?

Question

Need to use an image of the molecular structure of concrete for a concept. Searched high and low for the thing. Cant find it!

Answer 1

Concrete is not a molecular material, which is why you can't find an image of it... It's a mixture of aggregate (tiny bits of rock or ash) held together by a cement.  (A cement is also a complex mixture, of calcium oxide and silicates with other metal oxides, including MgO and Al2O3.)

Different types of concrete are made from different ingredients, so there isn't one single structure or formula.

Instead of molecular structures you might have better luck finding microphotographs.  Looks like this site has some nice ones: http://www.concrete.cv.ic.ac.uk/durabili...
