| 摘 要： | 利用磷酸铵镁水泥对普通硅酸盐水泥砂浆进行修补,并设计试验研究了其修补性能。结果表明,磷酸铵镁水泥修补材料的强度较好,28 d抗压强度可达77.5 MPa；磷酸铵镁水泥修补材料与旧有普通硅酸盐水泥砂浆的粘结性能良好,较小的M/P比值有利于早期粘结性能的提升；磷酸铵镁水泥修补处的抗渗水性较好,减小M/P比值或增大水胶比会降低抗渗水性。

| Abstract: | Portland cement mortar was repaired by magnesium ammonium phosphate cement ( MAPC ) . The repair performance of MAPC was studied by designed test. The results show that the strength of MAPC repair material is good, and the 28 d compressive strength can reach 77. 5 MPa. The bond performance between MAPC repair material and the old ordinary portland cement mortar is good. The smaller M/P ratio is beneficial to the improvement of early bond performance. Repair division of MAPC have excellent anti-permeability performances. Decreasing the ratio of M/P or increasing the ratio of water to cement reduces the anti-permeability. |
