Mar 31, 2020 Westend61/Westend61/Getty Images. The basic mix ratio for concrete is one part water, two parts cement and three parts sand. An alternative ratio is one part cement, two parts sand and three parts gravel with enough water added until the mixtures reaches the consistency of thick mud. Lime is also a common additive to the mix.

Concrete consists of three basic components: water, aggregate (rock, sand or gravel), and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and hardened into the durable material with which we are all familiar.
