Cement: The Glue, Not the Backbone
Let's get one thing straight: cement is like the glue in a sandwich. It holds everything together, but it's not the main event. The sand, gravel, and other aggregates are the bread and fillings that provide the bulk and strength. Cement on its own is about as useful as a one-legged duck in a shooting contest.

Why Sand is Your BFF
Sand is the unsung hero of the concrete world. It fills the gaps between the larger aggregates, improving workability and strength. It's like the supportive friend who always has your back. Without sand, your cement mixture will be weak, prone to cracking, and generally unhappy.
