    Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as

  • Concrete Wikipedia

    Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens. In modern usage, most concrete production takes place in a large type

  • Moisture Control in Concrete Production Agg

    Using moisture sensors to control slump in concrete production. Concrete has a worldwide consumption of approximately 1 tonne per person per year, making it the second most consumed substance on Earth after water. It is comprised of three elements: aggregate and sand (filler), cement (binder) and water.

  • Aggregates America's Cement Manufacturer

    Aggregates strongly influence concrete's freshly mixed and hardened properties, mixture proportions, and economy. Consequently, selection of aggregates is an important process. Although some variation in aggregate properties is expected, characteristics that are considered include:

  • Aggregate in Concrete The Concrete Network

    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.

  • The Effect of Aggregate Properties on Concrete

    The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

    Fine aggregate consists of natural sand, manufactured sand, or a combination thereof with particles that are typically smaller than 0.2 inches. Coarse aggregate consists of either (or a combination of) gravel, crushed gravel, crushed stone, air-cooled blast furnace slag, or crushed concrete, with particles generally larger than 0.2 inches.

    Although concrete is a popular building material, many people are unfamiliar with concrete production, as well as how concrete is delivered and poured. When we pour concrete for a floor, we often use a fine aggregate mix and incorporate color. During the finishing process, the concrete can be scored, stamped or textured.
