Abstract

PURPOSE:To manufacture a block product of good strength by applying pressure a plurality of times to a product material of low water to cement ratio and molding a block product of given thickness. CONSTITUTION:When the total compression volume of a back layer material 10 is set at T, the first stage compression process compresses, for instance, 1/3 to 1/2 only of said total compression volume T as the reference pressure R. The reference pressure R should be a pressure not to generate a rough and dense aggregate distribution in the back layer 10. Then, as the second stage compression process, the remaining volume of the back layer material 10 (1/2 T) only is pressure compressed similarly to said compression process. In that case, compression is started from a state that around 1/3 to 1/2 of T only is compressed, which enables the back layer material 10 to absorb the water content of a surface layer material 9 to be permeated over the whole area of the back layer 10, and a block product 12 is formed.
