    Aggregates that predominantly show size fractions in a limited range of sizes (such as the 20 mm and 10 mm aggregate in Figure 1) are called 'uniformly' graded, while aggregates that show a continuous gradation of size (sand in Figure 1) are called 'well' graded or continuously graded.

    Does Aggregate Size Affect Concrete Shrinkage? Concrete

    Q.: I've heard that pea-gravel concrete shrinks more than concrete made with a larger maximum-size coarse aggregate. Why? A.: Cement paste shrinks and most aggregates don't, so increasing the aggregate content (reducing the paste content) reduces shrinkage. To produce a workable concrete, a small maximum-size aggregate such as pea gravel requires a higher sand content than does a larger

    Aggregates for Concrete - GreenSpec

    Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.

    Aggregate (composite) - Wikipedia

    Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel

    Aggregate serves as a reinforcement to add strength to composite materials such as concrete. Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve.

    Quality Counts. Make sure that your concrete producer purchases good-quality aggregate as verified by regular aggregate test results in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates." A history of good performance of a local aggregate also provides an indication of how well the material performs in service.
