Study on mechanical properties of alkali-resistant basalt fiber reinforced concrete
Highlights The influence of BF and ABF on the mechanical properties of concrete was investigated. The addition of ABF is beneficial to improving the strength of concrete. The bonding of ABF and concrete matrix is better compared to BF.
Abstract The alkali resistant basalt fiber (ABF), which are the modified basalt fiber with the property of the alkali resistant, has potential application in concrete. This study investigated the alkali resistance of ABF and the unmodified basalt fiber (BF) by soaking the fibers into the simulated alkaline solution of concrete. The effects of BF and ABF on the mechanical properties of concrete were studied. The results showed that, the compressive strength, flexural strength and splitting tensile strength of the concrete with the addition of 0.1% ABF were increased by 2.5%, 17.2% and 12.1%, respectively. The measurements of mercuryintrusionporosimeter (MIP) and scanning electron microscopy (SEM) indicated that the addition of ABF improved the pore size distribution of concrete. Moreover, the bonding between the fibers and the matrix of concrete was enhanced.
