Alternative processing procedures for recycled aggregates ...

As a matter of fact, recycled concrete aggregates are mainly composed of two phases , , namely old aggregates and old mortar paste. Consequently, the standard procedure generally adopted for the design and production of ordinary concrete (i.e., with natural aggregates), cannot be applied when Recycled Aggregates Concrete is used.

Qualities & Properties of Aggregates for Concrete

Aggregates play a significant role in construction. They are used in the production of concrete. The total volume of concrete normally consists 75% to 85% volume of aggregates that makes the cost of concrete relatively low. Aggregates act as structural filler in the concrete.

Concrete Production Process| marstllaroilconcrete.com

26-7-2016· Aggregates. Aggregates are coarse materials like gravel, sand or crushed brick that are added to the cement and water. The cement binds to them, holding them in place. Although aggregates are often thought of as a filler, they’re actually a key component of concrete. Between 60 and 80 percent of concrete is made of aggregates. Other ...

Aggregates - Portland Cement Association

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.
