煅烧温度对钛石膏物理性能影响的研究

摘要

研究了不同煅烧温度对钛石膏物理性能的影响，并对其影响机理进行了探讨。研究表明，随着煅烧温度的升高，钛石膏力学性能呈现先升高后降低的趋势。当煅烧温度为180℃时，钛石膏的煅烧产物主要为半水石膏相，此时钛石膏试样的力学强度达到最大，其2 h抗折强度为0.94 MPa，2 h抗压强度1.87 MPa,绝干抗折强度1.54 MPa,绝干抗压强度2.52 MPa。%The paper studies the influence of the calcination temperature on the physical properties of titanium gypsum, and its influence mechanism. As a result, as the calcination temperature increases, the mechanical proper⁃ties of titanium gymsum increase first and then decrease. When the calcination temperature is 180℃, the main cal⁃cined product is hemihydrate gypsum phase, and the mechanical strength of the titanium gymsum specimen achieve maximum, its 2 h flexural strength is 0.94 MPa, 2 h compressive strength is 1.87 MPa, oven dry flexural strength is 1.54 MPa, oven dry compressive strength is 2.52 MPa.
