Abstract: A porous formed plate includes 35 to 70% by mass of a substance not involved in a pozzolanic reaction; 20 to 61.5% by mass of a cement; 1 to 3% by mass of synthetic fibers; and 2.5 to 7% by mass of a pulp, wherein, in a pore size distribution of the formed plate that is determined by a mercury intrusion method, a ratio (B)/(A) of a pore volume (B) in a range of 6 to 560 nm with respect to a pore volume (A) in a range of 660 to 9,100 nm is 1.70 to 6.0.

Abstract: Provided is a fiber-reinforced carbonated hydraulic inorganic molded plate having a high bulk specific gravity, a high flexural strength, and a small dimensional change rate per specific gravity. (1) A fiber-reinforced carbonated hydraulic inorganic molded plate including: a cement component, a pulp, and a reinforcing fiber having an aspect ratio in a range of 40 to 1000; and being a carbonation-cured molded plate. (2) A molded plate being a cured product of a composition including at least a cement component, a pulp, and a reinforcing fiber, wherein the molded plate is a fiber-reinforced carbonated hydraulic inorganic molded plate and has a carbonation reaction rate of higher than or equal to 30%.
