Questions & Step-by-Step Solutions

What is the effect of adding too much water to a concrete mix?
  • Step 1: Understand that concrete is made of cement, water, sand, and gravel.
  • Step 2: Know that water is needed to help the cement bond with the other materials.
  • Step 3: Realize that if you add too much water, it creates more spaces (porosity) in the concrete.
  • Step 4: Understand that these extra spaces make the concrete weaker.
  • Step 5: Recognize that weaker concrete performs poorly and may crack or break easily.
