CE Blog: Concrete Mixed Design Method (BS Method)

The volume of mix is multiplied with the constituent contents obtained from the concrete mix design process to get the batch weights for the trial mix. The mixing of concrete is according to the procedures given in laboratory guidelines. Firstly, cement, fine and course aggregate are mixed in a mixer for 1 minute. Then, water added and the cement, fine and course aggregate and water mixed approximately .
