Properties of ceramic fiber reinforced cement composites

Chemical stability of basalt fiber in alkaline solution

“…Also, not only does the large amount of Fe determine the color of the basalt fibers, due to the large atomic weight of Fe, the density of basalt fibers is larger than that of glass fibers [3]. It can also be noted that, since both fibers contain similar amounts of SiO 2 , it can be assumed that the composition ratio of SiO 2 with Al 2 O 3 and the chemical interaction of Al 2 O 3 with -OH group plays a much larger role in the chemical resistance of basalt fibers [4].…”

“…SiO 2 , which is the main component of glass fibers, exhibits the following chemical reaction when exposed to alkaline conditions [4,12].…”

“…Despite the many efforts to improve the shortcomings of glass fibers, due to the basic attributes of the chemical structure, there are more improvements that are needed to be made. Although basalt fibers has great promise as a replacement raw material for glass fibers, there are still many factors that need improvement such as economic feasibility and the stability of quality [2][3][4]. However, as the application possibilities of basalt fibers as a construction material is high, there are efforts to use the environmentally friendly material of basalt as a construction material.…”

Response of Refractory Cement Based Composite to Gradual Temperature Loading

“…The surface treatment significantly influences behaviour during elevated temperature, because it provides the cohesion between fiber and the composite´s matrix [23]. These types of fibers are used even for ordinary concrete, when 0.2% of volume improved the dynamic characteristics of ordinary reinforced concrete [24]. However, ceramic fibres could be successfully used also for ceramic refractories for severe applications [25].…”

Efficiency of Plastic Fibres Waste on the Physico-Mechanical Properties of Mortars in Hot-Dry Conditions

“…We noted M0, the mortar without fibres, M0.5 and M1, the mortars reinforced respectively by 0.5 and 1 % of polypropylene fibres waste. We have prepared prismatic samples (40x40x160) mm 3 , which were conserved after demoulded in water for 14 days and then under weeks of curing, and then the strengths decrease considerably. After 14 days curing in this environment, the increase of the flexural strength for mortars M0 (mortar without fibres), M0.5 (mortar reinforced by 0.5 % of fibres) and M1 (mortar reinforced by 1 % of fibres) was about 116, 86 and 101 % respectively compared to reference strengths.…”
