What is water to cement ratio?

Answer 1

• Water/cement ratio law states that the strength of concrete is only dependent upon water/cement ratio provided the mix is workable.
  
• Strength of concrete primarily depends upon the strength of cement paste.
• Similarly, the strength of the paste increases with cement content and decreases with air and water content.
  

Answer 2

1. Water cement ratio is defined as the indicator of strength is the ratio of water used compared to the amount of cement.
2. Lower the W/C ratio, higher will be the strength.
3. A minimum of W/C ratio 0.3 should be adopted.
   

Answer 3

0.5

Answer 4

1:5
