Concrete is a mix of portland cement, an aggregate, water and other additives that give the mix certain characteristics. Aggregates vary depending on scale, colour, strength: All measurements are given as volumes, or relationships of volume. The dry materials are mixed first. Water is added to the dry mix. Do not add too much water; the drier the mix, the stronger the final product. (Excess water stays trapped in the cured cement.) How wet to make the mix is a function of the process: casting in a mold will need a wetter mix that slumps into place. Applying the mix to a wire mesh will need a drier mix that feels more like clay and stays in place until it sets.
