Use of Recycled Aggregate Concrete JEA Conferences

aggregate), and old hardened concrete can be recycled and used as aggregate in new concrete or as fill and pavement base material. 2. Economic factors. Recycling concrete is an attractive option for governmental agencies and contractors alike. Most municipalities impose tight environmental controls over opening of new aggregate sources.

The Use of Recycled Concrete Aggregates (RCA) for

Because recycled aggregate contains mortar from the original concrete, it is more porous and absorptive than many natural aggregates. Recycled aggregate had water absorption of 9.6%. The workability of concrete, as the amount of recycled aggregate was increased, the concrete required more water to maintain adequate

Use of Recycled Concrete Aggregate in PCCP: Literature

Properties and Characteristics of Recycled Concrete Aggregate A concrete pavement's strength and performance is very dependent on the aggregates used to produce the concrete. Recycled concrete aggregates are different in many ways from aggregates as shown in Table 1. Table 1. Comparison of typical aggregate and recycled concrete

MAKING CONCRETE FROM RECYCLED MATERIALS

MAKING CONCRETE FROM RECYCLED MATERIALS Researchers work toward developing reliable standards for the use of recycled concrete aggregates in new concrete. The Issue Making concrete out of recycled concrete aggregate, or RCA, can be a sustainable and costsaving alternative to other aggregates. However, the quality of concrete made with

Recycled Aggregates—Profitable Resource Conservation

the recycled material is used as aggregates for road base. The remaining onethird of recycled material is reused as aggregates for new asphalt hot mixes (Kelly, 1998). Concrete Recycling Aging U.S. infrastructure, decreasing availability of landfill space, and environmental concerns work together to increase concrete recycling.

Recycled Concrete as Aggregate for Structural Concrete

Recycled concrete aggregate (RCA) is generally produced by twostage crushing of demolished concrete, and screening and removal of contaminants such as reinforcement, paper, wood, plastics and gypsum. Concrete made with such recycled concrete aggregate is called recycled aggregate concrete (RAC). The main purpose of this work is to determine
