摘要 |
Process for the production of concrete tiles by means of cutting a block of concrete mixture, characterized in that said block of mixture is subjected to a preliminary curing at ambient pressure and temperature for a duration of at least 24 hours (or to a low-pressure steam treatment at a temperature <100 DEG C) until the compression strength reaches a value of at least 20 MPa, and to a second treatment with steam in an autoclave. The cement tiles thus obtained may be bonded to the floor using a normal setting layer of cement mortar, without giving rise to any problems of detachment. <IMAGE> |
