Book Description
Self-Compacting Concrete (SCC) is a relatively new building material. Nowadays, its use is progressively changing the method of concrete placement on building sites. However, the successful use of SCC requires a good understanding of the behavior of this material, which is vastly different from traditional concrete. For this purpose, a lot of research has been conducted on this area all over the world since 10 years. Intended for both practitioners and scientists, this book provides research results from the rheological behavior of fresh concrete to durability.

Book Description
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.

Book Description
Dear Colleagues, We are pleased to organize the Sixth International RILEM Symposium on SCC and the Fourth North-American Conference on the Design and Use of SCC, held on Sept 26-29, 2010 in Montreal, Quebec, Canada. The RILEM series of symposia started in 1999 in Stockholm, followed by Tokyo in 2001, Reykjavik in 2003, Chicago in 2005, and Ghent in 2007 with a steadily increasing number of papers, participants, and interest from across the globe. Due to the growing success of SCC, regional conferences have been organized, such as the North-American Conference on the Design and Use of SCC held in Chicago in 2002, 2005, and 2008; the International Symposium on Design, Performance and Use of SCC held nd in Changsa, China in 2005 and in Beijing, China in 2009; as well as the 2 International Conference on Advances in Concrete Technology in the Middle East: SCC held in Abu Dhabi in 2009. It can be concluded that these regional Conferences and Symposia were highly successful and reached a far more international audience than anticipated. Nearly 100 papers were submitted for these proceedings from which the International Scientific Committee selected 37 contributions covering a wide range of timely and original subjects from around the world. We would like to acknowledge the input of the International Scientific Committee for providing critical input to guarantee high quality of these peer-reviewed proceedings. We invite you to explore a wealth of information in the electronic proceedings.

Book Description
The State-of-the-Art Report of RILEM Technical Committee 228-MPS on Mechanical properties of Self-Compacting Concrete (SCC) summarizes an extensive body of information related to mechanical properties and mechanical behaviour of SCC. Due attention is given to the fact that the composition of SCC varies significantly. A wide range of mechanical properties are considered, including compressive strength, stress-strain relationship, tensile and flexural strengths, modulus of elasticity, shear strength, effect of elevated temperature, such as fire spalling and residual properties after fire, in-situ properties, creep, shrinkage, bond properties and structural behaviour. A chapter on fibre-reinforced SCC is included, as well as a chapter on specialty SCC, such as light-weight SCC, heavy-weight SCC, preplaced aggregate SCC, special fibre reinforced SCC and underwater concrete.

Book Description
Volume is indexed by Thomson Reuters BCI (WoS). Self-Compacting Concrete (SCC) refers to a 'highly flow-able,non-segregating concrete that can be spread into place, fill the formwork,and encapsulate the reinforcement without the aid of any mechanicalconsolidation. SCC is regarded as one of the most promising developments inconcrete technology due to significant advantages over Conventional Concrete(CC). In this study cracking caused by external loads in reinforced SCC andFRSCC slabs is examined experimentally and analytically. The mechanismsassociated with the flexural cracking due to the combined effects ofconstant sustained service loads and shrinkage are observed. One of theprimary objectives of this study is to develop analytical models thataccurately predict the hardened mechanical properties of SCC and FRSCC.Subsequently, these models have been successfully applied to simulatetime-dependent cracking of SCC and FRSCC one-way slabs.

Book Description
"The main objective of this study was to investigate the performance of sustainable self-consolidating concrete (SCC) for highway bridge structures. Two types of concrete were utilized in this study: high volume fly ash-self consolidating concrete (HVFA-SCC) and high strength-self consolidating concrete (HS-SCC). This dissertation consists of two major parts: a laboratory study developing and investigating the overall performance of HVFA-SCC and a field study of time-dependent field-based behavior of HS-SCC in Bridge A7957 MO, USA. In the first part, an experimental program was conducted to develop a new class of SCC incorporating up to 70% cement replacement with fly ash. Three replacement levels (50%, 60%, and 70%) by weight were selected to quantify the effect of cement replacement on the structural performance of HVFA-SCC. Shear behavior and bond performance of HVFA-SCC were investigated in the laboratory. The shear behavior program consisted of twelve full-scale beams, and the bond performance program consisted of twelve full-scale splice test specimens. Analysis of the HVFA-SCC data indicated that concrete with up to 70% cement replacement can be considered for the production of sustainable SCC. The second part of this dissertation presents the total prestress losses and thermal behavior of Bridge A7957 constructed with HS-SCC. A health monitoring system was established on this bridge to monitor the time-dependent behavior of bridge girders using VWSGs and a data acquisition system. HS-SCC girders were monitored for more than two years' worth of field-based data. Both measured prestress losses and thermal data (uniform temperature and thermal gradients) were compared to the current design specifications. Results showed that the investigated specifications require some modifications to accommodate the material composition of HS-SCC"--Abstract, page iv.
