Why do you need straw to make brick?

Straw is used in brick-making, particularly in adobe bricks, to improve the structural integrity and durability of the final product. It acts as a binding agent that helps hold the clay or mud together, reducing cracking as the bricks dry. Additionally, straw enhances insulation properties and contributes to a lighter weight, making the bricks easier to handle and transport. Overall, incorporating straw can lead to stronger, more resilient building materials.
