Play Sand: It’s Fun, But Not So Strong
Play sand is, as the name suggests, designed for play. It's soft, rounded, and generally free of impurities. Sounds perfect for building castles, right? But when it comes to mixing with cement, it's a different story.
Imagine trying to build a brick wall with ping pong balls. That's kind of what you're doing when you use play sand in cement. The rounded grains don’t lock together as well as the angular grains found in construction sand. This means your cement mixture will be weaker and more prone to cracking.
QuickTip: Focus more on the ‘how’ than the ‘what’.
Why Play Sand is a No-Go
- Lack of Grip: Play sand’s smooth, rounded particles don’t interlock well with cement, leading to a weaker mixture.
- Impurities: While play sand is often sterilized, it might contain contaminants that can affect the cement's strength and durability.
- Consistency: Play sand can vary in grain size, which can impact the consistency of your cement mix.
What to Use Instead?
If you're serious about your concrete or mortar project, opt for construction-grade sand. It's specifically designed for these purposes and will give you a much stronger and more durable end product.
Remember: Using the right materials is crucial for any construction project. Don't let your inner child convince you that play sand is the way to go. Your future self will thank you.
QuickTip: Reading carefully once is better than rushing twice.
