将钢渣微粉以不同的掺量掺入水泥中进行砂浆实验与水化热实验,研究钢渣微粉潜在胶凝性的发展。结果表明:钢渣微粉的掺入会降低水泥的胶凝性能,但钢渣微粉水化后期的潜在胶凝性比水泥高。钢渣微粉可以提高砂浆的流动度、折压比,大幅降低... 将钢渣微粉以不同的掺量掺入水泥中进行砂浆实验与水化热实验,研究钢渣微粉潜在胶凝性的发展。结果表明:钢渣微粉的掺入会降低水泥的胶凝性能,但钢渣微粉水化后期的潜在胶凝性比水泥高。钢渣微粉可以提高砂浆的流动度、折压比,大幅降低水泥的水化热。 展开更多

Displaced and unstable pelvic ring injuries have been treated mainly by open reduction and internal fixation. The goal of treatment relies on restoration of pelvic anatomy with stable internal fixation, allowing early mobilization of the patient.The symphysis pubis dislocation (〉25 mm) is consistent indication for anterior internal fixation.3 In most situations, the fixation of the displaced symphysis pubis requires extensive exposure, which may lead to complications including blood loss, neural or vascular injury, postoperative infections, wound healing problems and heterotopic bone formation. 展开更多

We present an unusual case of an un- stable pelvic fracture during pregnancy period, who suf- fered fetal death and splenic rupture simultaneously which developed massive delayed hemorrhage in abdomen. When considering potential causes of fetal death, direct trauma to the uterus, placenta, or fetus was not associated with a higher fetal mortality rate, compared with maternal hemorrhage. A cesarean section and splenectomy could res-cue the maternal life from the hemorrhage situation. Suc- cessful treatment of these rare cases is possible with careful pre-, peri-, and post-operative evaluation of the mother and fetus by a multidisciplinary team. 展开更多
