FIELD: building materials production. SUBSTANCE: solid carbonic acid (having particles up to 1 mm in size) is mixed with gypsum binder and with mixing water. Said solid carbonic acid (being prepared by throttling of liquid carbonic acid from pressure 50-60 atm to pressure 1 atm) is fed into mixing water simultaneously with adding gypsum binder into it. Semihydrous gypsum is used as said gypsum binder. EFFECT: increased strength of porous material.
