  • Concrete Mix Ratio

    Introduction to Concrete Mix Ratio. Concrete mix ratio is the mixture of materials that make concrete. The materials are cement, stone aggregate, sand and water. When mixed producing concrete. The cement, when mixed with water, creates a paste that coats the sand and aggregate. The water causes the cement to hydrate, and a chemical reaction ...

  • Using Recycled Concrete Aggregate | Specify Concrete

     · Crushed concrete has been in use since the ancient times, only to be integrated with gravel, sand, and cement to ensure durability. The practice was first recorded in the 1860s. US construction companies were reluctant to use the technique at first, since crushing cured concrete proved to be much more costintensive in terms of labor.

  • What are the Correct Concrete Mixing Ratios

    Such a mix combines cement, sand, and gravel in the correct mixing ratios and requires only the addition of water to create fresh concrete. These bags are basically a 1 : 2 : 4 concrete mix ratio. These concrete mixture ratios are designed for the concrete to reach full strength at or around 28 days old.
