Concrete Mix Design Using (DOE - British) Method

Description

CONCRETE MIX DESIGN

Concrete mix design is the process of finding the right proportions of cement, sand, and aggregates for concrete to achieve target strength in structures.

• Mix Design is the science of determining the relative proportions of the ingredients of concrete to achieve the desired properties in the most economical way

DOE METHOD OF CONCRETE MIX DESIGN:

The British method of concrete mix design, popularly referred to as the "DOE method", is used in the United Kingdom and other parts of the world and has a long-established record.

The DOE method of mix design is applicable to all types of concrete mixes. The method originates from the "Road Note No 4" which was published in Great Britain in 1950. In 1975 the note was replaced by the "Design of Normal Concrete Mixes", published by the British Department of the Environment (DOE). In 1988 the "Design of Normal Concrete Mixes" was issued in a revised and updated edition to allow for changes in various British Standards.

DOE mix design generally involves the following stages.

Step 1: Determine the target mean strength

Step 2: Determine the water/cement ratio

Step 3: Determine the water content

Step 4: Determine the cement content

Step 5: Determine the total aggre­gate content

Step 6: Determine the fine aggregate content

Step 7: Determine the mix proportion of the concrete mix for a given volume
