Download or read book The Behavior and Durability of Self consolidating Concrete written by Aly Said and published by . This book was released on 2015 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report focuses on the production of self-consolidating concrete using local materials from Las Vegas, Nevada. Tests were conducted on eight self-consolidating concrete mixtures having two different percentages of fly-ash replacement (25% and 35%) as well as the inclusion of the superplasticizer ADVA 195 and the viscosity modifying admixture V-MAR 3. The fresh properties tested were flowability, passing ability, and stability. Mechanical properties evaluated were compressive strength, splitting tensile strength, and the modulus of elasticity. The durability of specimens produced from the mixtures was tested for chloride ion resistance, sulfate resistance, and salt scaling. A key outcome of these tests for both fresh and hardened properties was that the mix design of self-consolidating concrete should be tailored according to the planned application (drilled shafts, precast products, repair concrete, etc....). Another key outcome was the importance mix design to accommodate the hauling time while maintaining consistent fresh properties of self-consolidating concrete at the delivery site. Recommendations for applications for self-consolidating concrete include using additional parameters to assess the suitability of the mixture to the designated application such as (T50, Jring), especially in critical applications where complications occur. And while additional testing may become a burden on the overall operation, it can be performed in trial batches and selectively during delivery. Another recommendation is to further investigate the use of techniques to control bleeding in large volume self-consolidating concrete casts.

Download or read book Concrete Recycling written by Francois de Larrard and published by CRC Press. This book was released on 2019-03-04 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book A Conceptual Model for Designing Recycled Aggregate Concrete for Structural Applications written by Marco Pepe and published by Springer. This book was released on 2015-12-12 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Properties of Self consolidating Concrete Containing Expanded Slate Lightweight Aggregate written by Mohamed M. Sadek and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis aimed to evaluate the performance of self-consolidating concrete using either lightweight fine expanded slate aggregate (LF) or lightweight coarse expanded slate aggregate (LC). The rheological and mechanical properties of the lightweight self-consolidating concrete (LWSCC) mixtures were evaluated, in addition to the impact resistance and the durability (including abrasion and salt scaling resistance). The variables in this study included the type of lightweight aggregate (LF and LC), lightweight aggregate volume, binder content (500 kg/m3, 550 kg/m3 and 600 kg/m3), and types of concrete (LWSCC, normal weight self-consolidating concrete and lightweight vibrated concrete). The research program was divided into three stages. The first stage included optimization of LWSCC using expanded slate aggregate to obtain mixtures with minimum possible density (while achieving acceptable fresh properties) and mixtures having a target density of 2000 kg/m3 with maximized compressive strength. The second stage included investigation on the mechanical properties and impact resistance, while the third stage covered the assessment of the durability of the optimized mixtures. The results showed higher flowability for the LWSCC mixtures when LF was used compared to LWSCC mixtures with LC. However, LWSCC mixtures with LF required more high range water reducer admixture to reach the acceptable level of flowability compared to LWSCC mixtures with LC. The results also revealed that LWSCC mixtures with LF had higher mechanical properties, impact resistance and abrasion resistance before and after the exposure to salt scaling compared to LWSCC mixtures with LC at the same density level. Additionally, the results showed that the stability of the LWSCC mixtures (using LC or LF) enhanced by increasing the binder content. Increasing the binder content also allowed for using more lightweight aggregate, thus resulting in lower density mixtures.
