Admixtures

  • Q. What are admixtures?

    Admixtures are those ingredients/materials that are added to cement, water, and aggregate mixture during mixing in order to modify or improve the properties of concrete for a required application.

  • Q. What major changes can be expected in the behavior of concrete in which admixtures have been used?

    Broadly the following five changes can be expected:

    1.Air entertainment

    2.Water reduction for better quality

    3.Acceleration of strength development

    4.Improving the workability

    5.Water retention

  • Q. How can you ensure that the admixture will perform as required?

    The best way to test the admixture is by making trial mixes with the concrete materials to be used on the job and carefully observing and measuring the change in the properties. This way the compatibility of the admixture and the materials to be used, as well a the effects of the admixture on the properties of fresh and hardened concrete can be observed. The amount of admixture recommended by the manufacturer or the optimum quantity determined by laboratory tests should be used.
