Size Effecton Recycled Concrete Strength and Its Prediction Model Using Standard Neutrosophic Number by X. Peng,Q. W. Yang,F. J. Qin Pdf

In recent years, research on recycled aggregate concrete has become a hot issue in the field of civil engineering. This paper mainly studies the size effects on compressive and tensile strengths of the recycled aggregate concrete. Firstly, four sets of recycled concrete cube specimens with different sizes are produced in the laboratory. Secondly, the experiments on compressive and tensile strengths are carried out to obtain the rules of the strength value with the change of the specimen size. Thirdly, a standard neutrosophic number is proposed and used in modelling the size effect law more reasonably. According to the experimental results, it was found that the compressive and tensile strengths of recycled concrete both have obvious size effects. In general, the strength value decreases gradually with the increase of specimen size. Using the standard neutrosophic number, the proposed new formula on size effect law is more suitable for tackling the indeterminacy in the experimental data.

Recycling of Offshore Concrete Structures by fib Fédération internationale du béton Pdf

The report confirms that removal, re-use wholly or in part, and complete demolition and recycling of CGS (Concrete Gravity Structures) are technically feasible. Governmental policy is consistently moving towards rewarding those industries that contribute to environmentally friendly management. Recycled material is an environmentally friendly alternative that incurs reduced consumption of virgin material and less waste disposal. There is no reason to believe that offshore concrete should be less suitable for recycling than other concrete. For some platforms the most suitable vessel for carrying the topside ashore may prove to be the CGS itself, as it has to be removed from its position anyhow. A successful removal, however, requires a well planned and controlled operation, necessitating a profound knowledge and understanding of the structure, both in its technical and operational aspects. An important instrument to acquire such knowledge are the records kept during the platform's history describing the main parmeters and events. The report treats the aspects of re-use, removal, demolition methods and recycling of materials and refers to all known international and national regulations in this field, adding a comprehensive list of references and usable internet links.

A Conceptual Model for Designing Recycled Aggregate Concrete for Structural Applications by Marco Pepe Pdf

This book reports on the physical and mechanical characterization of Recycled Aggregate Concrete (RAC), produced through a partial-to-total replacement of ordinary aggregates with what have been dubbed Recycled Concrete Aggregates (RCAs). It proposes a theoretical framework for understanding the relationships between RCAs and RCA, and for predicting the resulting behavior of RAC. The book demonstrates that in the case of RAC two additional parameters have to be taken into account than with ordinary aggregates, due to the composite nature and higher porosity of RCAs. By extending Abrams’ Law for Recycled Aggregate Concrete, it represents a first step in the formulation of a general model for predicting the properties of RAC. The theoretical approach presented here addresses an important gap in the literature and is expected to stimulate new research on the use of this more sustainable form of concrete in structural applications.

Adhesion Problems in the Recycling of Concrete by Pieter C. Kreijger Pdf

The building explosion during the years 1945-1960 will inevitably lead to increased demolition in the next decades since the lifetime distribution of structures no longer fulfills its functional social requirements in an acceptable way. In the building period mentioned there was a great increase in reinforced and prestressed concrete construction. Consequently there is now more and more concrete to be demolished. Increasingly severe demands will be made upon demolition technology, including the demand for human- and environment-friendly techniques. On the other hand, the possibility of disposing of debris by dumping is steadily diminishing, especially close to major cities and generally in countries with a high population density. At the same time in such countries and in such urban areas a shortage of aggregates for making concrete will develop as a result of restrictions on aggregate working because of its effect on the environment and because of the unavailability of aggregate deposits due to urban development. From the foregoing it follows that recycling and re-use of environment- and human-friendly demolished and fragmented building rubble should be considered. The translation of this general problem into terms of materials science is possible by forming clear ideas of adhesion and cohesion: the whole process of demolition, fragmentation, and recycling or re-use of concrete is to break the bonding forces between atoms and molecules and to form new bonds across the interfaces of various particles of either the same nature or a different nature.

Concrete Recycling by Francois de Larrard,Horacio Colina Pdf

The concrete industry consumes thirty billion tons of aggregate annually, almost all from non-renewable natural sources. Demolition produces a growing amount of materials which are legally usable and readily available. If not used locally they must be transported and landfilled. Also, demolition generally takes place close to new construction sites: recycling promotes shorter transportation distances, a must for improving the overall environmental footprint of the construction world. This book encompasses all aspects of this current trend: How recycled aggregates are obtained and their properties. Improving their quality through phase selection or separation. Incorporating concrete from demolition into the cement production process and the properties of the product obtained. What are the properties of concrete incorporating recycled concrete aggregates at various replacement levels, throughout the lifecycle of the material, from the fresh state to the long-term, including durability and fire. How recycled concrete can be optimised for various uses. How this new structural material can be managed in reinforced concrete construction. Solid experience from a series of experimental sites, and drawing on the Recybéton project, which lasted more than 5 years and gathered about 50 partners (from both academia and industry). Specific issues in recycled concrete quality control. National practices in the most advanced countries, and the main national and European standards. Achieving a sustainable process.
