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).

Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2.

NOTE 2—Size No. 1 is that specified for concrete sand in Specification C33; Size No. 2 is that specified for masonry mortar in Specification C 144; and Sizes 8 and 89 are standard sizes as given in Specification C33. 4.2 Aggregates of gradations other than those covered by Table 1 are permitted if all of the requirements of 4.2.1, 4.2.2,

Jul 12, 2024 · There are seven standard sieves for fine aggregates ranging from No. 100 to 3/8” and 13 standard sieves for coarse aggregates ranging from No. 16 to 4”. For example, coarse aggregate has specific grading requirements for each different size from #1 to #8.

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 below).

This gradation chart is for general reference only. The percent range represents the percent passing for each sieve size. For specific material requirements or questions about your project needs, please contact customer service at 1-888-766-4242.

This table details the sieve size, the percentage of aggregate retained on each sieve, and the cumulative percentage passing. Analyzing this data allows for comparison with the grading requirements specified in ASTM C33 for various concrete applications.
