Recycled aggregates and particularly, recycled concrete aggregate substantially affect the properties and mix design of concrete both at fresh and hardened states since it is known by high porosity
BCA GreenmarkThe Samwoh Green Concrete plant is capable of producing Green concrete which contains recycled materials such as washed copper slag, recycled concrete aggregate and green cements for the construction industry. It can also produce high performance concrete and other concrete mixtures.
Apr 01, 2012 · The recycled materials used in this study consisted of ground granulated blast furnace slag (GGBFS), recycled concrete aggregate (RCA) and crushed waste glass. The GGBFS, or slag cement, was used as a replacement for the cement. The RCA and waste glass were used to replace the coarse and fine aggregates, respectively.
Green Concrete from Sustainable Recycled Coarse The use of recycled aggregate for the production of concrete involves breaking demolished concrete into materials with specified size and quality. These materials can then be combined to produce aggregate of a predetermined grading and hence can be used in concrete.
Performance of Seawater-Mixed Recycled-Aggregate Jan 01, 2020 · The use of seawater and recycled coarse aggregate (RCA) in concrete mixtures leads to the production of a very sustainable concrete. The potential risk of steel reinforcement corrosion (due to chloride in the seawater) in such mixtures may be eliminated when considering plain concrete or noncorrosive reinforcement (e.g., fiber-reinforced polymer).
Recycled Aggregate in Concrete:Use of Industrial, Construction and Demolition Waste focuses on the recent development which the use of various types of recycled waste materials as aggregate in the production of various types of concrete.
Using Recycled Aggregates for Concrete ProductionSep 15, 2020 · Utilising high-quality recycled aggregates and its on-site concrete batching plant, Velde Pukk AS supplies the construction industry with a CE-certified concrete from 100% recycled sand and aggregates. Likewise, AF Gruppen, also based in Norway, produces high-quality washed sands and aggregates which have also Norwegian standard certification.Recycled Aggregates - Portland Cement Association
