STRENGTH PROPERTIES OF SIFCON USING OF ARTIFICIAL FIBERS

Next to water, concrete is the most used material worldwide for construction of any desired shape or dif erent structure. Concrete has low strength, low ductility and energy absorption. Dif erent concrete require dif erent degrees of durability depending on the exposure environment and properties desired. Concrete ingredients, their proportioning, placing and curing practices, and the service environment determine the ultimate durability and life of concrete. For this purpose to improve the concrete toughness and reduce the amount of defects by adding a some fibers to the concrete for this situation SIFCON type concrete is preferred and the fiber are uniformly distributed and it is dif erent from fiber reinforced concrete (FRC). Slurry-infiltrated fibrous concrete (SIFCON) can be considered as a special type of fiber concrete with high fiber content. The fiber content of FRC generally varies from 1to3 percent by volume, but the Fiber content of SIFCON varies between 5 and 20 percent. The network is then infiltrated by a fine liquid cement-based slurry or mortar. It is not having coarse aggregate only have cement and sand or any cementitious material. In view of the above, the objectives of this study are to investigate and provide information about strength of SIFCON, mainly resistance to abnormal loads, impact loads and earthquake loads. Here straight stainless steel and E type glass fiber are used with dif erent volume of fraction, i.e. 6%,8%,10%,12% and cement, sand, fly ash are used 1:1:0.5. The compressive strength of SIFCON is increased 26% when comparing to M30 concrete.
