The production of tailor made high strength and high performance concrete are made by incorporating silica fume into the normal concrete and it is a routine one in the present days. The mix proportioning is intricate and the design parameters are increased due to the incorporation of silica fume in conventional concrete. The aim of this paper is to look into the different mechanical properties ...

Based on the bending experiment for two-span continuous post-tension beams with unbounded tendons and externally applied CFRP sheets, the analysis of the stress increment of unbonded tendons is monitored in the loading process. Since self-compacting concrete (SCC) is a suitable innovation,, understanding the implementation of this type of concrete on the ultimate unbonded tendon stress is criti...

Self-compacting concrete can be defined as the concrete which requires no vibrations and can flow around obstructions, encloses the reinforcement and fills up the formwork completely under its self weight. Over the last ten years, significant amount of work has been carried out on self-compacting concrete all over the world. In countries like Japan, Sweden, Thailand, UK etc., the knowledge of S...

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 concrete (scc) is a highly fluid yet stable concrete that can flow consistently under its own weight, pass between bars, and fill in formwork without the need of compaction. the application of scc effectively resolves the difficulties of concreting in situations with complicated formwork and congested reinforcements. in this paper, the bond between scc and steel reinforcement wa...

The incorporation of silica fume into the normal concrete is a routine one in the present days to produce the tailor made high strength and high performance concrete. The design parameters are increasing with the incorporation of silica fume in conventional concrete and the mix proportioning is becoming complex. The main objective of this paper has been made to investigate the different mechani...

In studies conducted to determine the workability of concrete, the bagasse ash and rice husk ash were added as a partial replacement for cement. Trial mixes with the varying water cement ratio, replacement percentage, quantity of super plasticizer and viscosity modifying agent, were prepared and tested. The results were used as the basis for defining three optimum cement replacement mix proport...

Concrete is a material that often used in the construction industry due to its strong compressive strength and durability. Currently, lot of research being done find new ways increase performance. One these ideas what led creation self-compacting. accepted as most cutting-edge development concrete building industry. Self-Compacting becoming more popular for usage overloaded reinforced construct...
