过硫磷石膏矿渣水泥混凝土中PSC浆磷石膏含量测定方法研究

Study of the Determination Methods of the PSC Pulp Phosphogypsum Content in the Excess-sulfate Phosphogypsum Slag Cement Concrete

通过分离过硫磷石膏矿渣水泥混凝土中的过硫磷石膏矿渣水泥浆,并测定各原料的SO3含量,然后根据各原料SO3的平衡关系,计算出了过硫磷石膏矿渣水泥混凝土中的过硫磷石膏矿渣水泥浆的磷石膏含量。经实验反复验证,显示磷石膏含量的测定误差均可在1.0%范围之内,可作为过硫磷石膏矿渣水泥混凝土生产过程中磷石膏配合比的日常控制和测定方法。

Through the separation of the Excess-Sulfate Phosphogypsum Slag pulp from the Excess-Sulfate Phosph-ogypsum Slag Cement Concrete,and the determination of the SO 3 content in each material,this study calculated the Phosphogypsum Content in the Excess-Sulfate Phosphogypsum Slag pulp of the Excess-Sulfate Phosphogypsum Slag Cement Concrete according to the equilibrium relationship of SO 3 in each material.Through repeated verification,it showed that the measurement deviation of the Phosphogypsum Content is within 1.0% range,so this method can be used to daily control and determine the mix proportion of the Phosphogypsum during the production of the Excess-Sul-fate Phosphogypsum Slag Cement Concrete.
