This study evaluated the use of recycled concrete as coarse aggregate in new concrete pavements. Recycled concrete aggregate (RCA) produced from demolished pavements in three geographically-dispersed locations in Washington state were used to perform testson aggregate characte ristics, fresh concrete propertiesand hardened concrete properties.
If 65% of recycled aggregate or above is used, each physical properties will drop greatly. However, if the portion of recycled aggregate adds to concrete is limited, it won't affect each property much. Based on the research and experiment test, "the maximum replacement of recycled coarse aggregate that can be used in concrete is 35%".
Arrangements can be made to haul concrete from a demolition site to the recycling plant, or, in some cases, recyclers are able to move portable recycling machinery to the plant site. In terms of the overall environment, recycling concrete greatly saves energy compared to mining, processing and transporting new aggregates.
Suitable for excavators weighing over 43 Ton, the crusher bucket BF 135.8 was created to meet the specific needs of crushing in quarries, for aggregates recycling operations in landfills, for volume reduction of materials resulting from demolition in large yards, or excavation, sewage systems and preparation of aggregates.
Aggregate base course (road base) The largest application of recycled concrete aggregate (RCA) is for the aggregate base course in road construction.This term refers to the center layer of the roadbed. A cross-section of pavement would show dirt, or subgrade, as the lowest of three levels, layered on top by aggregate base course, and finally capped on top by pavement, either concrete or asphalt.
Raw Materials The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 38-43 lb (17.2-19.5 kg).
