  • HOW TO DECIDE MAXIMUM SIZE OF COARSE

    On the other hand in smaller size aggregates the surface area is increased which increases w/c ratio and lower strength is achieved. In general for strength upto 200 kg/cm 2 aggregates upto 40 mm may be used and for strength above 300 kg/cm 2 aggregate upto 20 mm may be used.

  • Classification of Aggregates as per Size and

    22-7-2016· Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70 to 80 % of

  • Aggregates

    Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.

  • Maximum Aggregate Size & Nominal Maximum

    By the CT 382 definition, the maximum aggregate size is 3/4" and the nominal maximum aggregate size is 1/2". In the November 2011 version of CT 202, nominal maximum aggregate size is defined as "one sieve size larger than the first size to retain more than 10%." By this definition the nominal maximum aggregate size for the material example

  • What nominal maximum sizes of aggregate are

    Because maximum aggregate size can impact concrete properties such as shrinkage, and also the cost of concrete, the largest aggregate size consistent with the requirements of 26.4.2.1 should be permitted. With the w/cm fixed, the larger the

  • The Effect of Aggregate Size on The Strength of Concrete

    several factors such as, mixing ratio, aggregate size, texture, coarse and fine aggregate, compaction method, curing period and some parameters have been discussed in literature review. The results showed the concrete aggregate size of 20mm has a 45.7% higher compressive strength than the concrete aggregate size of 10mm.

    For convenience, 6.3mm can be referred to as "6mm", and 31.5mm as "32mm".The ratio of D/d must not be less than 1.4. Aggregates are then designated as being either G C (coarse), G F (fine), or G A (all-in).
