  • Different Types Sizes of Aggregate for Concrete ...

    2018-8-11  Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate.

    Proportion of fine aggregate to coarse aggregate (by mass) : Generally 1:2 but subject to an upper limit of 1:1.5 and a lower limit of 1:2.5. Note: The proportion of fine aggregate to coarse aggregate should be adjusted from upper limit to lower limit progressively as the grading of fine aggregate becomes finer and the maximum size of the ...

  • What is the size of coarse aggregate used in

    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...

    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.

    2019-10-17  20 mm 10 mm 4.8 mm Fine Flaky aggregate are the aggregates whose least dimension is less than 3/5th of its mean dimension i.e. the mean dimension of an aggregate passing through 40 mm sieve and retained on 20 mm sieve is 40+20/2 = 30 mm. Now if the least dimension is less than18 mm (3/5 x 30 = 18 mm) then the aggregate is flaky.
