چکیده

Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good self compacting ability. The interest in reducing costs while improving workability, shrinkage tendency and the modulus of elasticity was leading to the results in this paper.

Durability Performance of Self Compacting Concrete Incorporating Alccofine and Fly Ash

The cost associated with the application of large volume of cement and synthetic admixtures was one of the major drawbacks of Self Compacting Concrete (SCC), which can be reduced by the use of supplementary cementitious materials (SCM). When the demand of cement reduces, the release of carbon dioxide (CO2) from cement industries will come down, which has a positive impact on global w...

Investigating properties of fresh and hardened self-compacting concrete made of recycled aggregates

Self-compacting concrete is a new high performance concrete with high ductility and segregation resistance. In recent years, construction material manufacturers have focused their attention on lightweight concrete and have strived to use lightweight concrete, if possible, in load-bearing parts of buildings. Concrete with both self-compacting and lightweight properties is favourable in this cont...

Developing a Cost-Effective Approach for Enhancing the Rheological and Mechanical Behavior of High Strength Self-Compacting Concrete

Despite the numerous advantages of using concrete with high strength capacity, the brittle behavior of high strength concrete (HSC) and higher production cost has limited its use in the construction industry. This research aims to develop a cost-effective approach for production of high strength self-compacting concrete with desirable performance in either compressive or tensile loading conditi...

Fibre - reinforced , self - compacting concrete flow modelled by smooth particle hydrodynamics

A Lagrangian particle-based method, the smooth particle hydrodynamics, is used to model the flow of ultra-highperformance, self-compacting concretes containing short steel fibres which behave like a non-Newtonian fluid described by a Bingham-type constitutive model. An incompressible smooth particle hydrodynamics method is used to simulate the flow after the kink in the shear stress against the...

Comparison of the Performance of Self Compacting Concrete

Self-Compacting Concrete Originally developed in Japan, SCC technology was made possible by the much earlier development of Superplasticisers for concrete. To compare the performance of SCC with Fly Ash 20%, Silica Fume 10%, Rice Husk Ash (5%, 10%, and 15%) as a partial replacement of cement, due to the high increase in construction which has brought a heavy demand for ingredients of concrete s...
