VERSTAERKTES GLASIERTES ZEMENTPRODUKT UND VERFAHREN ZU SEINER HERSTELLUNG.

摘要

A glazed cement product and method for manufacturing thereof wherein the glazed cement product comprizes a foam light-weight aggregate, reinforcing steel under pretension or stress-absorbing layer around the reinforcing steel; an action of generating crack caused by a difference of coefficient of thermal expansion between the reinforcing steel and a portion of cement material while burning and cooling are carried out is absorbed by the foam light-weight aggregate, the stress-absorbing layer or pretension given to the reinforcing steel; a reaction of unreacted cement component is promoted by the hydration to harden for recovering mechanical strength.
