I have a minor pet peeve about a term people use all the time. The term is "cement", when describing concrete.
What's the difference? Cement is a powder. The powder, usually "Portland Cement" is the binder for concrete, which is a mixture of coarse aggregates (usually crushed rock), fine aggregates (usually sand) and the cement, which comes in many varieties.
Although it seems simple, the chemicals used in concrete, including set retarders and liquid air for insulating qualities, make for a multitude of specialty products. The varieties can be simple, or complex for special applications, such as a high strength, flowable concrete I once used to pour through 8 inch holes in a bridge deck.
So, when someone says: "That looks like a cement truck ahead." they're probably referring to a concrete truck, which is called a redi-mix batch truck. A cement truck is a tractor trailer combination, with the trailer being a hopper.
Calling a concrete truck a cement truck is like calling a cake a pan of flour.
Now you know the difference. You can fascinate your friends with your new knowledge.
In Case You've Wondered
My blog is where my wandering thoughts are interspersed with stuff I made up. So, if while reading you find yourself confused about the context, don't feel alone. I get confused, too.
If you're here for the stories, I started another blog: scratchingforchange.blogspot.com
One other thing: sometimes I write words you refuse to use in front of children, or polite company, unless you have a flat tire, or hit your thumb with a hammer.
I don't use them to offend; I use them to embellish.
