Maximum Aggregate Size

Maximum Aggregate Size. The maximum size of coarse aggregate is one of the factors that controls water demand to achieve certain workability. It also dictates quantity of fine aggregate content needed for producing cohesive mix. For a given weight, higher the maximum size of aggregate, lower is the surface area of coarse aggregates and vice ...

  • AASHTO #57 Stone Specs

    AASHTO #57 stone as defined by quarries, state agencies, etc. is an open-graded, self-compacting aggregate blend of size 5, 6, & 7 stone. This material cannot be 'compacted' in a true sense, but can be properly oriented with compaction equipment. This is particularly important when using #57 stone under Flexi-Pave surfaces.

  • Advantages of Using Maximum Size of Aggregate in Concrete

    Aggregate gradation is a process in which the constituents are evenly distributed according to their shape & size that helps the concrete to achieve a maximum density. To achieve the dense mix of concrete, all the ingredients need to be distributed properly in the mix.

  • Aggregates - Portland Cement Association

    Grading limits and maximum aggregate size are specified because these properties affect the amount of aggregate used as well as cement and water requirements, workability, pumpability, and durability of concrete. In general, if the water-cement ratio is chosen correctly, a wide range in grading can be used without a major effect on strength. ...

    3. The advantage of small aggregate in the water-ratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand. It appears that optimum maximum size, so far as strength is concerned, will vary for different aggregates, different cement factors, different test ages and probably other conditions. 4.

  • ACI 211.1: Maximum Aggregate Size For Concrete Mix Design

    In this post I shall discuss maximum aggregate size that can be used in design. Large maximum sizes of aggregates produce less voids than smaller sizes. Hence, concretes with the larger-sized aggregates require less mortar per unit volume of concrete, and of coarse it is the mortar which contains the most expensive ingredient, cement.

    Similarly, higher flexural strength is obtained at a given w/cm with smaller nominal maximum size aggregate. Data from compression tests of concrete containing very large aggregates, 100 mm (4 in.) and over, are conflicting because of limitations in the size of the test specimens and testing machines.
