Questions & Step-by-Step Solutions

What is the primary purpose of cement in concrete?
  • Step 1: Understand that concrete is made up of different materials, including aggregates (like sand and gravel) and cement.
  • Step 2: Recognize that cement is a powdery substance that, when mixed with water, forms a paste.
  • Step 3: Learn that this paste coats the aggregates and fills the spaces between them.
  • Step 4: Realize that as the cement paste hardens, it binds the aggregates together, creating a solid structure.
  • Step 5: Conclude that the primary purpose of cement in concrete is to act as a binding agent that holds everything together.
