    Key PointsAggregate ExtractionWaterMore About Concrete• ‘Aggregate’ is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled.• Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.• Aggregates in any particular mix of concrete are selected for their durability, strength, workability and ability to receive finishes.• For a good concrete mix, aggregates need to be cle...

    aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete’s freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed

  • Aggregates for Concrete greenspec.co.uk

    • 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. • Aggregates are divided into either ‘coarse’ or ‘fine’ categories. Coarse aggregates are particulates that are greater than 4.75mm.

  • STANDARD SPECIFICATIONS for GENERAL CONCRETE

    The concrete work under this specification shall include all clearing and grubbing, preparation of subgrade, furnishing and placing co ncrete, shouldering, and construction of fills and aggregates used. Weighing equipment shall be arranged to permit making compensation for

  • 4 Aggregate Specifications and Requirements

    Certain substances in aggregates are undesirable for use in portland cement concrete. Therefore, the Specifications limit the amount of deleterious constituents to a level consistent with the quality sought in the final product. Organic impurities are the only concern in fine aggregates. Section 904.02

  • Cement Standards and Concrete Standards

    ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
