Experimental research on the fundamental mechanical properties of presoaked basalt fiber concrete

Abstract

Presoaked basalt fiber concrete (PBFC) is a new kind of concrete reinforced with random short presoaked basalt fibers. In the paper, the applicability of the presoaked basalt fiber (PBF) as a strengthening material was investigated through various experimental works for mechanical characteristics and strengthening effects by changing its dosage and length, and compared with ordinary concrete. Experimental researches showed that: adding the presoaked basalt fiber on the condition of constant in matrix concrete, the influence on compressive strength was not noteworthy, but tensile strength was improved significantly. Form the results of the tests, it is concluded that presoaked basalt fiber can significantly reduce the brittleness of concrete, improving the toughness and deformation resistance. The presoaked basalt fiber can be regarded as a strengthening material for concrete structures. © Tsinghua University Press, Beijing and Springer-Verlag Berlin Heidelberg 2011.
