The research objectives were to investigate the feasibility of using recycled concrete aggregate (RCA) as a base course material in asphalt pavement, to evaluate the physical properties of RCA, and to develop practical and reliable guidelines and specifications. The tasks included literature review, sample collection, laboratory testing, accelerated performance testing and pavement distresses ...

Mix design procedure for recycled aggregate concrete ...

Use of recycled aggregate concrete (RAC) is one such attempt and is an answer to some of the problems in constructional engineering. The concept of using RAC is now gaining popularity and research in this direction has gained momentum. In this paper, the authors have identified the most suitable method of mix design for RAC, from amongst the available conventional methods of mix design. An ...

Behavior of FRP-Confined Recycled Brick Aggregate

06/12/2020  Reprocessing brick waste into recycled brick aggregate (RBA) to fabricate new concrete [i.e., recycled brick aggregate concrete (RBAC)] has proved to be an effective solution. RBAC is generally used as nonstructural concrete owing to its inferior mechanical and durability properties compared with natural aggregate concrete (NAC). To achieve ...

Prediction on CO 2 uptake of recycled aggregate concrete

Abstract:. Carbonation of concrete is a process which absorbs carbon dioxide (CO 2).Recycled aggregate concrete (RAC) may own greater potential in CO 2 uptake due to the faster carbonation rate than natural aggregate concrete (NAC). A quantitative model was employed to predict the CO 2 uptake of RAC in this study. The carbonation of RAC and the specific surface area of recycled coarse ...

Effect of Recycled Concrete Aggregate ... - SAGE Journals

This study focuses on characterizing several recycled concrete aggregate (RCA) sources, developing concrete mixture proportions that incorporate RCA as coarse aggregate, and investigating the effect of coarse aggregate properties on the main mixture proportion parameters [i.e., cement content, water demand, and water–cement (w/c) ratio]. Four aggregate types were investigated: one control ...

Use Of Recycled Aggregate In Concrete - IJERT Journal

If good quality aggregate is used for the production of new concrete, the recycled aggregate has no influnce on the compressive strength, regardless of the replacement ratio of natural coarse aggregate with recycled aggregate. The same findings are found for concrete tensile strength (splitting and flexural). The modulus of elasticity of concrete also decreases with increasing recycled ...

Durability Studies on the Recycled Aggregate Concrete in ...

Since China hosted the Olympic Games in 2008, a mass of construction and demolition (CD) wastes were produced with the rapid urbanization construction. Recycling the CD waste into recycled aggregates (RA) is an effective method for reducing the amount of CD wastes. Many studies on the properties of RA and the durability of recycled aggregate concrete (RAC) were conducted in China

Recycled Aggregate - an overview ScienceDirect Topics

However, due to the general availability of virgin aggregates (at least at the regional or national scale), often most of the recycled CD debris is used as road base or subbase material, as recycled aggregates are generally less expensive or “valuable” than high-quality concrete aggregate. To favor the use of recycled aggregate, and to enhance the recycling rate of CDW, Green Public ...
