Static mechanical properties of reactive powder concrete reinforced with basalt fibers
In this article, the effect of length (6, 12, and 18 mm) and volume fraction (0, 0.3%, 0.6%, 0.9%, 1.2%, and 1.5%) of basalt fibers (BFs) on the static mechanical properties of reactive powder concrete (RPC) was studied. The binding of BFs to matrix in BFRPC was investigated at the micro‐level by scanning electron microscope (SEM). The experimental results showed that BFs effectively improved the splitting tensile strength and flexural strength of the RPC, despite the effect of different lengths. With the increase in the BFs volume fraction, the splitting tensile strength and flexural strength first increased and then decreased. And, for compressive strength, 6 and 12 mm BFs can improve the strength, while 18 mm BFs caused strength recession. Compared with the experimental groups, it was found that the overall performance of RPC with the BFs length of 12 mm and the volume fraction of 0.9% was the best. The research results have great significance in the engineering application of BFRPC.
