The most commonly used concrete mix design is called a normal-strength concrete, which consists of Portland cement, sand, aggregate (typically gravel or crushed stone), and water. The proportions of these ingredients are typically expressed as a ratio, such as 1:2:3:0.5, which represents the ratio of cement to sand to aggregate to water.
