Characterization of Cement Composites With Basalt- Based Reinforcement: Interfacial Transition Zone and Mechanical Properties
Original language description
Basalt fibers are today used mainly as reinforcement in polymer based composites in e.g. automotive industry but several types of basalt fibers based products is increasingly utilized also in civil engineering. The primary motivation for using of basalt-based reinforcing elements (either in form of Basalt Fiber Reinforced Polymer bars or chopped basalt fibers as dispersed reinforcement) is its better stability – compared to mild steel – in the marine environment. Most of the currently produced basalt fibers are directly after the drawing out from the melt treated by an organosilane sizing. This kind of sizing is beneficial when the fibers are used in organic (epoxy or vinyl ester resin) matrix. Unfortunately in the cementitious matrix a different – inorganic – sizing would be more favorable for the wetting and adhesion in this inorganic matrix. The fibers in state “as received” (i.e. with organosilane sizing) worked well in terms of bending strength of cement paste. However the sizing removal with acetone can improve the contact between fibers and matrix thanks to chemical interaction of basic cementitious environment and “glassy” basalt fibers. This observation implies the direction of future research.
