COLD HARDENING CASTABLE MATERIAL AND METHOD FOR EXECUTION OF THE SAME

PURPOSE: To obtain a cold hardening castable material capable of correcting a long time required to the demolding which is a defect of a heat-hardening castable material, carrying out the demolding in an early stage even at normal temperature under unfavorable hardening conditions and suppressing th...

Zusammenfassung:	PURPOSE: To obtain a cold hardening castable material capable of correcting a long time required to the demolding which is a defect of a heat-hardening castable material, carrying out the demolding in an early stage even at normal temperature under unfavorable hardening conditions and suppressing the cracking and structure embrittlement caused by steam in curing and provide a method for execution thereof. CONSTITUTION: This cold hardening castable material is obtained by adding a thickening agent in an amount of 0.01-2 pts.wt. expressed in terms of outer percentage to 100 pts.wt. refractory aggregate having a controlled size and then adding a setting agent in an amount of 0.1-1.0 pt.wt. expressed in terms of the outer percentage thereto. The characteristic of this method for execution of the castable material comprises adding the thickening agent in an amount of 0.01-2 pts.wt. expressed in terms of outer percentage to 100 pts.wt. refractory aggregate having the controlled size, adding the setting agent in an amount of 0.1-1.0 pt.wt. expressed in terms of the outer percentage to the resultant cold unhardening kneaded material having the fluidity just before the execution, kneading the prepared mixture and executing the casting of the resultant castable material. The castable material can be pumped under pressure in executing the casting thereof.
