ACI concrete mix design method

ACI concrete mix design method. ACI recommends a relationship between compressive strength and w/c ratio. Water demands for aggregates sizes are summarised in relation to the concrete workability (consistence) required. This leads to an estimate of cement content and aggregate content from an assumed concrete plastic density.
