THE EFFECT OF SINGLE AND HYBRID FIBRES ON FIBRE REINFORCED SELF COMPACTING CONCRETE PRODUCED WITH HIGH LEVEL OF FLY ASH USAGE
Abstract :
The aim of this paper is to present results of investigation carried out on fresh and mechanical properties of Fibre Reinforced Self Compacting Concrete (FRSCC) produced with fly ash which is an industrial waste material. Concrete industry is an important one between the industry branches for sustainability. In this study, high level of fly ash was used to reduce Portland Cement (PC) consumption as well as CO2 emission through the use of that waste material. For this purpose, a control Self Compacting Concrete (SCC) and 10 FRSCCs were designed applying slump flow, V-funnel and L-box tests to determine fresh concrete properties. In the design of FRSCC, both single and hybrid FRSCC mixes were produced using 3 macro and 1 micro steel fibres in different lengths and aspect ratios. Hybrid FRSCC mixes were prepared using each macro fibres together with micro fibre at two different percentages (50% and 75%) by weight. After design process, cubic and prismatic concrete specimens were produced to determine hardened properties. Flexural tensile and compressive strength tests were performed on the concrete specimens at the ages of 3, 7, 28 and 90-days. The test results showed concrete mixes including macro fibres gave the higher tensile strength properties, although they gave the lower fresh concrete properties.
