Plastic Shrinkage Cracking and Workability of Fibers SCC Composite

Compared to fiber reinforced concrete (FRC), self compacting concrete (SCC) is the new generation type of concrete with high flowability and good resistance to segregation. This type of concrete can be further extended when combined with fiber and can create a type of composite material. In this article, polypropylene and a new type of steel fibers were used as resin in SCC as matrix. The experimental effect of volume, length, and aspect ratios of the fibers on plastic state of this composite material is reported. For this aim, different tests on plastic phase such as L-box, slump flow diameter, J-ring and column segregation were carried out on SCC fibers included and excluded of nano particles. The plastic test results were shown that this type of fibers can be successfully used to design SCC and nano SCC composite and reached acceptable values on plastic state.
