  • Mixed Design: Purpose and Objects | Concrete Technology

    In a concrete mix, the relative proportions of the fine and coarse aggregates are one of the important factors which affect the strength of the concrete. For dense concrete, it is essential that the fine and coarse aggregates be well graded. The locally available aggregates generally do not conform to the standard grading's. In such situations the aggregates should be combined in suitable ...

  • Concrete Mix Proportioning

     · A concrete mix in which the proportions of cement, aggregate and water are adopted is called as nominal mix. It is not necessary that such a mix will give the desired strength and properties. For example, nominal mix proportions of M15 is 1:2:4. Nominal mix is not used for grades higher than M20. It is used for ordinary concrete works only.
