methods such as heating and rubbing and mechanical grinding have been developed in order to improve the quality of recycled aggregates by removing the attached pastemortar. e amount of pastemortar in waste concrete is about between and , but relative research is very limited .Read More
Jun 10, 2014018332In this study, the effects of fine recycled concrete and glass aggregate on mechanical and durability performance of concrete were investigated. The waste concrete and glass were crushed, sieved and re-mixed to fulfill the same gradation as the available 04 mm crushed limestone aggregate size fraction. The recycled aggregates were substituted for fine aggregate as 0, 15, 30, 45 and 60Read More
Some aggregate refining methods such as heating and rubbing and mechanical grinding have been developed in order to improve the quality of recycled aggregates by removing the attached pastemortar. The amount of pastemortar in waste concrete is about between 20 and 50, but ...Read More
Jul 07, 2019018332Recycled concrete aggregate RCA is traditionally limited to nonstructural applications. Although the crushing process results in weak mortar particles and surface cracks throughout the RCA, RCA concrete can be employed as rigid pavement materials after its mechanical strength has been improved.Read More
The first upgrading stage is sufficient to improve the quality of the recycled aggregates. The second stage did not provoke any further improvement. Upgraded recycled concrete sands had an improved quality compared to the simple recycled concrete sand. Although, the quality of the primary limestone sand was higher than the upgraded sand.Read More

Concretes consisting of portland cement OPC, silica sand, gravel, water, and recycled PET particles were developed. Specimens without PET particles were prepared for comparison. Curing times, PET particle sizes, and aggregate concentrations were varied. The compressive strength, compressive strain at yield point, and Young modulus were determined. Morphological and chemical compositions of ...Read More
The properties of recycled coarse aggregate and the slump, the physical and mechanical properties and durability of recycled aggregate concrete were studied through tests. The results indicate that the slump, compressive strength and durability of concrete with recycled aggregate are lower than that of concrete with natural aggregate when recycled coarse aggregate fully absorbs water.Read More
Single-edge notched beam, compression, and split-tensile tests were performed. For the specific recycled coarse aggregate RCA and virgin aggregate types studied, the total fracture energy of an RCA concrete mixture was improved by 53 by blending it with virgin coarse aggregate.Read More

Aug 01, 2018018332The possibility is that the aggregates being recycled go through mechanical grinding, churning, and other treatment methods for BM removal which may also beak the angular particle shape resulting in more spherical shapes leading to pronounced ball-bearing effect of aggregates in fresh concrete. This may lead to increased slump.Read More
