1. Nominal Concrete Mix Ratios. The specifications for concrete prescribed these proportions of cement, sand, aggregates, and water. These mixes of the fixed cement, sand, and aggregate ratio that ensures adequate strength are termed nominal mixes. Nominal concrete mixes offer simplicity and under normal circumstances, have a margin of strength above that specified.

Mar 31, 2020 More water, cement or sand can be added if the mixture is too wet or dry. Below is an example of a sand to cement mix ratio recommendation from a cement manufacturer. Concrete - 1 part cement, 2 parts concreting sand and 3 parts 20 millimeter aggregate. Mortar - 1 part cement, 4 to 5 parts building sand.
