I cringed when I read this. Concrete isn't dry. There is always
water retained in the matrix. Heated, it can flash into steam and
explode small chips of concrete and whatever it was that was
hot enough to explode it up into the air.

It is best to use dry sand. If you can, heat it before each use to
make sure it is dry.

And between uses keep it covered as you never know when
a cat is going to come by.
