Abstract
Disclosed herein is a fiber reinforced cementitious composition comprising a cementitious binder and at least one synthetic inorganic reinforcing fiber type, wherein the synthetic inorganic reinforcing fiber type comprises at least one of a man-made mineral fiber type such as basalt fibers, an aluminosilicate wool fiber type or an alkaline earth silicate wool fiber type.
Claims19
A fiber reinforced cementitious composition comprising:
- a cementitious binder;
- about 0.1% to 9% by weight amorphous fibers derived from basalt comprising silicon dioxide (SiO2) and aluminum oxide (Al2O3), wherein the amorphous fibers derived from basalt have a length between 3 and 15 mm and a diameter between 8 and 50 μm;
- at least one filler;
- about 0.1 to 8% by weight organic reinforcing fibers;
- wherein the amorphous fibers derived from the basalt are dispersed in the cementitious binder.
A fiber reinforced cementitious composition comprising about 20 to 45% by weight cementitious binder, about 35 to 68% by weight of at least one filler, about 0.1% to 9% by weight basalt fibers, about 3 to 8% by weight cellulose fibers, about 0 to 8% by weight of at least one density modifying filler, about 0 to 6% by weight of at least one or more additive(s).
