The right concrete mix ratio can solve problems and the wrong mix can create them. ACI 211.1 notes that the "selection of concrete proportions involves a balance between economy and requirements for placeability, strength, durability, density, and appearance." Finding the right balance to achieve all these requirements comes mainly from experience.
