The Good News: Sand Isn't ALWAYS Mandatory
Yes, believe it or not, Portland cement can be a social butterfly. It can mingle with other aggregates besides its sandy soulmate. Crushed rock, gravel, even leftover bits of concrete (just be sure they're clean!), can all be used to create a chunky, functional concrete mix.

- Cement dust is no joke: Wear a mask and gloves to avoid irritation.
- Safety glasses are your friend: A rogue cement speck in the eye is a real party pooper.
- Work in a well-ventilated area: Cement fumes can be unpleasant.
Now that we've covered the safety essentials, let's get mixing!
