| 中文摘要: |
| 本文通过向磷石膏中外掺可溶性磷，研究了可溶性磷含量对硅酸盐水泥与外加剂相容性及其强度的影响。研究结果表明，磷石膏中可溶性磷的含量影响着水泥与外加剂的相容性，外掺H3PO4 、H2PO4-、HPO42-时，随其掺量的增加，硅酸盐水泥与外加剂的相容性逐渐变差。相对于天然石膏而言，磷石膏中可溶性磷的含量仅引起硅酸盐水泥早期强度有所降低。 |
| 英文摘要: |
| In this paper, the influence of soluble phosphorus content on the compatibility and strength of Portland cement and admixture was studied by adding soluble phosphorus into phosphogypsum. The research results show that the content of soluble phosphorus in phosphogypsum affects the compatibility of cement and admixture. When H3PO4, H2PO4- and HPO42- are added, the compatibility of Portland cement and admixture becomes worse with the increase of its content. Compared with natural gypsum, the content of soluble phosphorus in phosphogypsum only causes the early strength of Portland cement to decrease. |
