Electrically Conductive Cement
zero_offset writes "The Tokyo Institute of Technology has announced a process for creating an inexpensive, nearly transparent, electrically conductive alumina cement. The conductivity is comparable to metal, and the transparency should be adequate for use in display panels. The process relies upon commonplace and inexpensive metals compared to the rare metals such as iridium currently used in display panels."
Cement = anything used to glue things together
Concrete = a building material composed of aggregates and cement
Concrete is used for buildings, roads, sidewalks, etc. The aggregate in that case is usually rocks. The cement is usually Portland cement. It's not correct to call it "cement", though people will usually understand what you mean.
But judging from the comments so far, not in this case. This isn't a replacement for Portland cement, and they're not talking about building materials. This is the kind of cement used to glue bits of LCD screens to each other.
Urine streams do not conduct electricity because they separate into droplets.
