Concrete Mixing Ratios - How To Make Concrete …
Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens. The strength of the concrete, after it cures, will be inversely proportional to the water/cement ratio. Basically this means the more water you use to mix the concrete (very fluid) the weaker the concrete mix.

What Is a Mixture in Chemistry? - ThoughtCo
2019-1-4 · A mixture is what you get when you coine two substances in such a way that no chemical reaction occurs between the components, and you can separate them again. In a mixture, each component maintains its own chemical identity. Typically mechanical blending coines components of a mixture, although other processes may produce a mixture (e.g., diffusion, osmosis).
