Aggregate sizes

Aggregate sizes

Very little aggregate in the medium size range Lots of different particle sizes thus very little void space. CIVL 3137 15 Uniformly Graded Aggregate 0 20 40 60 80 100 100 10 1 0.1 0.01 Percent Passing Opening Size (mm) 1 3/ 8 4 8 16 30 50 100 200

  • Classification of Aggregates Based on Size Classification of Aggregates Based on Size

    The most common size of aggregate used in the concrete mix is 20 mm for coarse aggregate and particle size less than 4.75 mm for fine aggregate. According to nature of the formation of aggregates, they are classified as: Natural Aggregates. Crushed Aggregates

    2. The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower water-ratio than the smaller sizes. 3. The advantage of small aggregate in the water-ratio strength relationship may or may not be sufficient to

    Aggregate specifications have an allowable range of different stone sizes, expressed as a percentage of the total weight of sample. This gradation specification is reported on a table or chart (see example ). The below nominal maximum size of an aggregate specification is defined as the

    1.Size of Coarse Aggregates: The size of the coarse aggregate depends on the use of the concrete is to be poured. For large-scale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used. For the simple construction of residential or other buildings, 20 mm is the maximum size will be used

    Fig 1: Aggregates used in production of concrete. The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate. In this article, we discuss the properties of the standard aggregates used in the production of concrete as per the American Standards (ASTM- C33/C33M)

    Oct 12, 2021 Size & Shape: Size & shape of aggregates directly has impact on strength of concrete, bond strength, workability of concrete, cement requirement and cost required for concrete. Rounded, elongated and flaky aggregates offer good workability but less bond strength and mechanical strength

    PA2A. Size 2 Inch Topsize. Description. PA2A is a mixture of coarse stone and crushed stone dust. It is used as a road base or an under-slab fill. It will drain and has a structural coefficient, making it ideal when stability and drainage are a concern. PA2A is a primarily clean material. 2RC/ 2A Modified
