磷酸镁水泥抢修抢建海洋环境海水拌合Magnesium-Phosphate Cement Emergency Repair The Marine Environment The Seawater Mixing

摘要:

根据海洋环境下抢修抢建的特殊性,利用海水与海砂制备海工磷酸镁水泥砂浆。通过测试其各龄期抗压强度,获得满足抢修抢建基本性能要求的最佳配合比,在此基础上,对海工磷酸镁混凝土、钢纤维增强海工磷酸镁水泥胶砂、海工磷酸镁水泥胶砂在海洋中的水上及水下两种不同环境的长期强度性能进行了初步研究。结果表明,三种海工磷酸盐水泥基材料在水上和水下的早期强度均能满足海洋环境下抢修抢建需要,但长期的强度变化规律不明显,需要进一步研究拌合海水对材料水化硬化作用以及侵蚀作用的影响。

According to the particularity of emergency repair and build under marine environment, marine engineering Magnesium-phosphate Cements were made with seawater and sea sand; the best mixture ratio was obtained which meets the requirement of emergency repair and build by testing compressive strength of each age. Based on previous research results, the primary research of long-term strength performance about Marine phosphate magnesium concrete, steel-fiber rein-forced Marine phosphate cement and Marine phosphate magnesium cement were performed in this paper. The research results show that early strength of all three kinds of Marine-phosphate cement overwater and underwater can meet the needs of the Marine environment emergency repair, but the long-term intensity variation regularity is not obvious. Further research about hydration and erosion influence of mix seawater should be performed.
