  • What is the size of coarse aggregate used in concrete?

    When the size of aggregate is greater than 4.75 mm ( say 5 mm) it is called coarse aggregate. Graded aggregates are used for better particle packing. The larger the size of aggregate lesser the cement required for same strength up to certain grade...

  • differences in concrete properties using 10mm to 20mm

    Depending on the mix design, either can be used to make essentially any range of concrete strengths. When you use a smaller aggregate, such as the 10mm as your nominal coarse aggregate size, the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate.
