Structural Behavior of Geopolymer Concrete Thin Wall
3.3. Recycled Concrete Aggregate (RCA) The recycled concrete is used as coarse and fine aggregates in the concrete mixes to reduce the rubble from the environment and produce a cheap local concrete. Locally available crushed concrete of size 12.5 mm is used as coarse aggregates and of the size 4.75 mm is used as fine aggregates.
Least-cost Control Optimization to Produce Concrete
Concrete mixes with different quantities of fly ashes and reclaimed concrete aggregates (RCAs) are optimized for various construction industry applications, namely residential housing far or close from the sea, economical residential housing, sustainable residential housing, and high-rise buildings.

Sustainability | Special Issue : Recycled Construction
Carbonation durability is an important subject for recycled coarse aggregate concrete (RAC) applied to structural concrete. Extensive studies were carried out on the carbonation resistance of RAC under general environmental conditions, but limited researches investigated carbonation resistance when exposed to chloride ion corrosion, which is an essential aspect for reinforced concrete
Mix Design for Pervious Recycled Aggregate Concrete
Nov 27, · Pervious concrete is a tailored-property concrete with high water permeability which allow the passage of water to flow through easily through the existing interconnected large pore structure. This paper reports the results of an experimental investigation into the development of pervious concrete with reduced cement content and recycled concrete aggregate for sustainable permeable pavement
recycled concrete Topic
Nov 30, · Recycled Concrete. Definition: hardened concrete that has been processed for reuse, usually as aggregate.- ACI Concrete Terminology. The reason for recycling is the reduction of waste in order to protect nature against pollution, the increasing shortage of suitable dumping grounds, and to save energy and natural resources.
Behavior of Reinforced Concrete Beams with Recycled
This paper investigates the flexural and shear behavior of reinforced concrete beams that use recycled concrete aggregates (RCA) as replacement for coarse natural aggregates (e.g., crushed stone, gravel).
Modeling the Failure Pattern of Prenotched Recycled
The reuse of recycled aggregate concrete (RAC) is being researched all over the world and lots of works are focused on the notched specimen to study the crack path of RAC. A mathematical algorithm of RAC meshing was presented to explore the failure pattern in RAC. According to this algorithm, the interfacial transition zone can be defined to be an actual thickness at the micron level. Further
Recycled Concrete Aggregate - an overview | ScienceDirect
Recycled concrete aggregate (RCA) are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low – below few per cent. For instance, British standard BS 8500-2 ( BSI, 2006 ) defines RCA as recycled aggregate with maximum masonry/fines content of 5%, maximum lightweight material/asphalt content of 0.5% and maximum other foreign materials content
Durability of Recycled Aggregate Concrete - Journal
Recycled aggregate concrete replaces natural concrete with various rates of restitution of natural aggregates into recycled aggregates. The choice of rate is essential in the quality of the finished concrete and depends on the mechanical and durability characteristics.
Evaluation of the concrete using low quality recycled
The purpose of this study was to evaluate the properties of recycled aggregate concrete (RAC) using low quality recycled aggregate with or without washing before usage. The recycled aggregate concrete evaluated in this study contained various amounts of low quality recycled aggregate

Durability Studies on the Recycled Aggregate Concrete in
Since China hosted the Olympic Games in , a mass of construction and demolition (C&D) wastes were produced with the rapid urbanization construction. Recycling the C&D waste into recycled aggregates (RA) is an effective method for reducing the amount of C&D wastes. Many studies on the properties of RA and the durability of recycled aggregate concrete (RAC) were conducted in China
Effect of recycled concrete aggregates on strength and
aggregates, such as crushed limestone and gravel, while the demolition of old concrete structures offers significant sourc-es of recycled concrete aggregate (RCA). Currently, RCA use in the United States is largely limited to nonstructural applications, such as road base. Uncertainty and variability
