Use of Recycled Aggregate in Concrete Seminar Report pdf

The utilization of recycled aggregate is particularly very promising as 75 per cent of concrete is made of aggregates. In that case, the aggregates considered are slag, power plant wastes, recycled concrete, mining and quarrying wastes, waste glass, incinerator residue, red mud, burnt clay, sawdust, combustor ash and foundry sand.

the recycled aggregate. The use of recycled aggregate generally increases the drying shrinkage creep & porosity to water & decreases the compression strength of concrete compared to that of natural aggregate concrete. It is nearly 10-30% as per replacement of aggregate. Recycling reduces the cost (LCC) by about 34-41% & CO 2 emission (LCCO 2

[PDF] Recycled Glass Concrete: Coarse and Fine Aggregates

Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones (coarse aggregate). However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials. While there is significant research on many different materials for aggregate substitutes such as granulated coal ash, blast

“RECYCLED PLASTICS USED AS COARSE AGGREGATE FOR

wastes in concrete will contribute to the sustainability of the concrete design and the natural environment. The project aims at use of recycled plastic in concrete as a partial replacement of Coarse aggregate. The maximum percentage of aggregate replaced by shredded plastic as been determined based on detailed experimental study.

Recycled construction and demolition concrete waste as

Dec 01, 2013· Three types of aggregates were used in this study which include natural sand as fine aggregate (NFA), coarse aggregates with grading of 4.75–20 mm were dolomite as natural (NCA) and the crushed concrete rubble as (RCA) which were collected from fifteen different sources of demolished buildings and landfill locations then crushed using a Hartle PC-160 mobile impact crusher shown in

Evaluation of Recycled Concrete for Use as Aggregate in

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.
