Synopsis:

The concrete being a composite material maximum amount of research work is going on to study its properties and its behavior with different materials to achieve optimum strength, economy or durability in construction.

The use of pozzolanic and cementitious materials in the  concrete industries has risen sharply during the last fifty years as mineral admixture [ Finely divided materials which are added to obtain specific engineering properties of cement mortar and concrete]. The reasons behind it are many. Cement, which requires high energy during its manufacturing process whereas the flyash, blast furnace slag and Silicafume are the industrial by-product, that are easily available, require little or no much of processing and have inherent cementitious properties.

Here Silicafume is relatively new material. The interest in the Silicafume started with the strict enforcement of air pollution controls in many countries, which implied that the industry had to stop releasing Silicafume along with other fine gases into the atmosphere. To find a solution to this problem, studied were initiated and after some investigation, it was found that the Silicafume could be used as a very reactive pozzolanic material in concrete. Investigations on the performance of Silicafume in concrete have been conducted in various countries. Research work has been reported on Silicafume in India and some applications have been reported in special structures.

Study of Silicafume and its effects on properties of resulting concrete based on literature study that consists:

Silicafume

Physical properties and chemical composition of Silicafume

Effects of Silicafume on properties of fresh concrete

Effects of Silicafume on properties of hardened concrete

Durability aspects

Applications of Silicafume          

Quality control of Silicafume concrete

Conclusion
