A cement reinforcing fiber obtained by impregnating an organic or inorganic fiber with a thermosetting resin, then coating it with a rubber solution or rubber latex, and curing it.

Cement reinforcing fiber

Cement is reinforced by mixing into a water-curable cement a reinforcing quantity of a fiber prepared by impregnating a carbon fiber with from 50-200 wt. % of a thermosetting resin, coating the impregnated resin with from 10-200 wt. % of a rubber solution or rubber latex, and then curing the coated fiber.

Modified carbon fiber reinforced cement

Cement mortar matrix and product are formed which are reinforced with a resin-impreganted twist-woven (Karami-ori) network of fibers which are oriented in the cement mortar in the direction of the maximum tensile stress yielded by the bending moment.

Fiber reinforced cement mortar product

A calcium silicate shaped product comprising a calcium silicate hydrate, a carboxyl group-containing copolymer latex, a coupling agent and a carbon fiber.
