Yeah, sand definitely is much harder than teeth (which in a normal vertebrate are based on apatite, at a Mohs hardness of 5). If it’s abrasion, that explains a bit, although it’s going to be much slower than an actual cutting action. A quick search indicates cement is at Mohs 5-7, so you theoretically could chew through an unusually soft sample.
It absolutely abrades the teeth faster than the cement, but rats are very social creatures. The point is that the Tupperware doesn’t stand a chance against even a single rat.
