  • Different Types Sizes of Aggregate for Concrete ...

    2018-8-11  Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate.

  • Aggregate Exposure Levels Custom Concrete Prep

    T here’s a time-honored adage about concrete which states that concrete is consistently inconsistent. Every single pour will be different from the next, with variations in color, cracking and overall flatness. While the polish finish is the end-game for custom concrete applications, aggregate exposure in custom concrete flooring can add a dimension of beauty and interest to the finished product.

  • Aggregate Sizing Explained - Chaney Enterprises

    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.
