| Abstract [eng] |
Self-compacting concrete mix is mostly known for its high flowability and high resistance to segregation and bleeding. These properties of concrete lead to finishing without using compacting or vibrating equipment. Addition of mineral admixtures, such as pulverized fuel ash, and superplasticizers improves the SCC properties and increase rheological parameters. This thesis discusses results of the experimental investigation on properties of SCC and SCFRC with the inclusion of polyolefin fibers with a difference of 0, 3, 6, 9 kg per m3, Glenium superplasticizer and containing PFA replacement rates of 0%,20%,40%,60% cement mass. The fresh properties of the concrete mix had been studied through segregation, bleeding, slump flow and slump flow time T500. The hardened properties of SCC had been studied through compressive and flexural strength, ultrasonic pulse velocity and CMOD test at age of 7, 28, 56 days hardening time. |
