Questions & Step-by-Step Solutions

What is the water-cement ratio for achieving a good quality concrete mix?
  • Step 1: Understand what the water-cement ratio is. It is the ratio of the weight of water to the weight of cement in a concrete mix.
  • Step 2: Know that a lower water-cement ratio leads to stronger concrete, but too low can make it hard to work with.
  • Step 3: Recognize that a water-cement ratio of 0.4 to 0.5 is ideal. This means for every 1 part of cement, you use 0.4 to 0.5 parts of water.
  • Step 4: Remember that using this ratio helps achieve good quality concrete that is strong and durable.
