Concrete: The Basic Mix

Too much water results in weak concrete. Too little water results in a concrete that is unworkable. Suggestions: If predetermined quantities are used, the method used to make concrete is to dry blend solids and then slowly add water (with admixtures, if used). It is usual to dissolve admixtures in the mix water before adding it to the concrete.
