Abstract: Self-compacted concrete (SCC) is a mixture must be carefully proportioned to achieve flowability and passingability without segregation. Usually, fibres are used to enhance the mechanical properties and post cracking behaviour of concrete. However, the addition of fibres might affect the fresh and hardened stage properties; moreover, exposure to harsh environment affects the concrete’s durability and long term performance.
In this paper, properties of a self-compacted concrete mixture with synthetic fibre prepared with local materials in the United Arab Emirates (UAE) were evaluated. Compressive strength, flexural strength and rapid chloride permeability tests were conducted. In addition, a group of specimens were exposed to 24-hour wet-dry cycles; for 21 days. Wet-dry cycles included soaking in indoor water tank and drying in air (outdoor environment). The peak temperature and humidity in UAE were 50° C and 89%; respectively. All results were compared to that of a base mix without fibre. Results of the investigation are presented and discussed.
