过硫磷石膏矿渣水泥混凝土中硅酸盐水泥的掺量对其性能影响极大，掺量过高后期强度将大幅度下降，掺量过低早期强度将会很低。该文通过试验发现：控制过硫磷石膏矿渣水泥混凝土中 PSC 浆的耗酸量，可以有效控制过硫磷石膏矿渣水泥混凝土中硅酸盐水泥的适宜配比，显著提高过硫磷石膏矿渣水泥混凝土的性能。过硫磷石膏矿渣水泥混凝土中的 PSC 浆滤液耗酸量应控制0.10~0.25 mmol/g 之间。

The mixing amount of the Portland cement had great impact on the performance of the Excess-Sulfate-phosphogypsum slag cement concrete.High addition of Portland cement leads to a significant drop of the later strength of the Excess-Sulfate phosphogypsum slag cement concrete;low addition of Portland cement leads to a significant drop of the early strength of the Excess-Sulfate phosphogypsum slag cement concrete.This study explored that controlling the acid consumption of PSC pulp in the Excess-Sulfate phosphogypsum slag cement concrete could effectively control the proportion of the Portland cement in the Excess-Sulfate phosphogypsum slag cement concrete at a suitable level, and thus improve the performance of the Excess-Sulfate phosphogypsum slag cement concrete.The filtrate acid con-sumption of PSC pulp in the Excess-Sulfate phosphogypsum slag cement concrete should be controlled between 0.10 mmol/g and 0.25 mmol/g.
