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.
Basics of concrete mix ratio. First, let's discuss what a mix ratio is. A mix ratio is the proportion of materials used in making concrete, including cement, aggregates (such as sand, gravel, or crushed stone), and water. Mix ratios are expressed as a series of numbers, such as 1:2:3, which means one part cement, two parts sand, and three ...
