Shear Behavior and Performance of Deep Beams Made with Self-Compacting Concrete

Ultra High Performance Self Compacting Concrete

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...

Torsion Behavior of Steel Fibered High Strength Self Compacting Concrete Beams Reinforced by GFRB Bars

This paper investigates experimentally and analytically the torsion behavior of steel fibered high strength self compacting concrete beams reinforced by GFRP bars. Steel fibered high strength self compacting concrete (SFHSSCC) and GFRP bars became in the recent decades a very important materials in the structural engineering field. The use of GFRP bars to replace steel bars has emerged as one o...

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...

High Performance Reinforced Concrete Beams made with Sandstone Reactive Aggregates

An investigation on the flexural behaviour of reinforced high performance concrete (HPC) has been conducted. Crushed sandstone known as reactive aggregate was used for both fine and coarse aggregates. In addition, mineral admixtures such as silica fume and fly ash combined with superplasticiser was used. The beams were made with concrete having compressive strength in the range of 74 88 N/mm 2 ...
