Sand and Gravel in Concrete | Shelly Company
The strength of the concrete is inversely proportional to the water/cement ratio. In other words, the more water you use to mix the concrete, the weaker the concrete mix. The less water you use to mix the concrete, the stronger the concrete mix. A mix with little water and more concrete mix will be dryer and less workable but stronger.
