The influence of fiber RC beams under flexure on the chloride-induced corrosion

Case Studies in Construction Materials, 2022
Corrosion of rebars is the main cause of the deterioration of reinforced concrete structures. In an aggressive marine environment, rebar corrosion occurs due to chloride ion penetration of the reinforced concrete (RC). This paper presents the findings of

FIBER-REINFORCED CONCRETE WITH MINERAL FIBERS AND NANOSILICA

Innovative technologies in science and education, 2015
Abstract The article presents the research results of mineral fiber use as a reinforcing component for concrete. The introduction of nanosilica to fiber cement compositions improves the corrosion resistance of the mineral fiber, due to the fact that nanosilica binds Ca(OH)2 during Portland cement hydration.
