To provide a method for manufacturing an inorganic cement composite plate having a high connecting strength and an excellent durability without bringing about a decrease in the strength for a long period.
The method for manufacturing the inorganic cement composite plate comprises the steps of forming a light-weight cement panel made of a fiber component or the like obtained by blending a cement and a light-weight aggregate as needed as an intermediate layer part, mounting a paste-like or mortar-like material containing the cement, a fine aggregate and the fiber component as main components on at least one side surface of the intermediate layer part to form a front layer part to a plural-layer plate, accelerated carbonation-curing the plural-layer plate to integrate the place. An organic polymer carbonation accelerator is previously contained together with the cement or the like in the plate to improve the integrating strength. Even after the integration, the strength can be maintained for a long period. It is preferred to start the accelerated carbonation-curing within 10 days in terms of a hydration material age of the front layer part as the latest.
