Self-Compacting Concrete Produced with Recycled Aggregates

Aims:

Dear Colleagues,

The subject of self-compacting concrete with recycled aggregates is greatly relevant to society, since there is an increasing demand from the recycled aggregates construction industry to adopt new processes to minimize its negative impacts on the environment. Self-compacting concrete has abundant advantages over conventional concrete and is gaining a significant fraction of the market. The use of recycled aggregates in concrete production presents a great environmental benefit through savings from the extraction of natural aggregates and the reduction of dumped material.

The advantages associated to the use of both concrete with recycled aggregates and self-compacting concrete have boosted an increase in research and a consequent need of literature. Combining these two themes has allowed allying the environmental and economic advantages of each of the materials, leading to an innovative material of great interest to the construction industry in general. The aim of this Special Issue is to explore the potential of use of recycled aggregates in the production of self-compacting concrete and to discuss new opportunities in this field.

Scope:

This Special Issue will incorporate research and review articles on exploring use of recycled aggregates in the production of self-compacting concrete. Despite some work already done on the subject, there is still room for more research on the subject. Potential topics include, but are not limited to:

• The characterization of fine and coarse recycled aggregates as well as the need to use them;
• Results of self-compacting concrete made with high content of fine and coarse recycled aggregates;
• Evaluation of its properties in the fresh state;
• Durability of self-compacting concrete with recycled aggregates in aggressive environments;
• Validation of the technical feasibility of self-compacting concrete with recycled aggregates;
• Establishment of acceptable maximum values for coarse and fine recycled aggregates incorporation in self-compacting concrete and other related design rules to be used in technical specifications;
• Life Cycle Assessment and Life Cycle Costs of self-compacting concrete with recycled aggregates;
• Case studies of the use of self-compacting concrete with recycled aggregates.
