There are many methods for determining the mixture proportions of concrete when compressive strength is the design criterion. However, there is not much information when other criteria, such as fracture energy, elastic modulus, or durability aspects, are specified. For these cases, a new mix design nomogram developed from well-established concrete relationships is reported. The application of this method is demonstrated by showing the influence of cement content, water-cement ratio, and aggregate-cement ratio on the compressive strength, modulus of elasticity, fracture energy, depth of carbonation, and permeability. The mixture design nomogram, apart from being a practitioner's tool, can also help the researcher select the most appropriate parameters for experimental studies.
