Self-Compacting Concrete - Opis:
- The main purpose of the study is to explore the effect of the plant fibers having different volume fraction on the fresh properties of the mix design of SCC such as filling ability, passing ability and segregation resistance as well as its influence on the compressive strength of the hardened SCC. The study started by conducting preliminary test on the aggregates needed in the construction of SCC. The aggregates were mixed together until uniform consistency was attained. Different volume fractions of CN and RS fibers were added on the mix design and molded in a cylindrical molder. The concrete were dried for 48 hours then placed in curing tank. Filling ability were tested by means of slump flow and T500 test. Passing ability were tested using J-ring while segregation resistance were tested using V-funnel and T5min. Hardened SCC with plant fibers were tested for its compressive strength. Based from the collected data, the filling ability were significantly affected by decreasing the slump flow of self-compacting concrete while increasing the time of SCC to spread to a diameter of 500 mm (T500). Furthermore, the passing ability and segregation resistance of SCC increases upon adding various volume fractions of CN and RS fibers. Statistical analysis further proves that there is significant difference between the normal SCC and the SCC with different percentages of CN and RS fibers. In addition, most favorable compressive strength were found when 0.05% CN fiber and 0.10% RS fiber were added to SCC after 7 and 28 curing days.
