    Normal weight aggregate: This type 3has unit weight of 1520-1680 kg/m. The concrete made with this type of aggregate has a bulk density of 2300-2400 kg/m3.


    • Fine aggregate: The European Standard uses the term fine aggregate in place of the term sand for material less than or equal to 4 mm in size. (Traditionally, British Standards defined this material as material passing 5.0 mm test sieve but retained on a 75 µm test sieve. (The symbol µm = micron which is one millionth of a metre or one thousand of a millimetre). The unit micron is not

  • Classification of Aggregates Based on Size and Shape

    When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. the size range of various coarse aggregates given

    increase in aggregate size results in a decrease in the compressive strength of concrete. Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used to make high-strength concrete, it is easier
