Najm: Compressive Strength and Stability of Sustainable Self-Consolidating Concrete Containing Fly Ash, Silica Fume, and GGBS, Jr. The problem of too low demoulding compressive strength is solved by incorprating composites of ground blast furnace slag(GBFS) and fly ash.
The demoulding compressive strength is too low for the high volume fly ash concrete mixtures.
The highly fluid nature of SCC makes it suitable for placing in difficult conditions and in sections with congested reinforcement.
This study aims to assess the effect of the amounts of fly ash and silica fume on strength and chloride penetration resistance of concrete. The optimum equivalent replace ratio is 10%, and super-substitute ratio is 20% according to the compression and flexural strength.
Experiment results are analyzed and compared with compressive strength development characteristic of fly ash high-performance concrete, and some valuable conclusions are gained.
Current Developments in Self-Compacting Concrete Introduction Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight.
The workability of fresh concrete, compression strength, spilt and flexural strength of recycled aggregate concrete with different content of fly ash at different curing age are tested.
Chaipanich: Compressive strength and chloride resistance of self-compacting concrete containing high level fly ash and silica fume, Material and Design, Vol. The addition of fly ash in recycled aggregate concrete has two methods, named equivalent replace and super-substitute technique.
