11 Factors that can Affect the Strength of Concrete
Factors that Affect the Strength of Concrete 01. Water/Cement Ratio. The ratio of the weight of water to the weight of cement is called Water/Cement ratio. It is the most important factor for gaining the strength of concrete. The lower w/c ratio leads the higher strength of concrete. Generally, the water/cement ratio of 0.45 to 0.60 is used.
