Cracking a bad habit: cement vs. concrete

Lately a bad habit has been hardening among writers and announcers: A few keep confusing “cement” and “concrete.”

The two words are not synonymous.

“Cement” is a powder that when mixed with water and other materials, like gravel, can solidify into a hard, stone-like substance called “concrete.”

So, you can’t have a “cement bridge” or a “cement building,” as that would suggest they are made of powder.
