Magnesium phosphate maritime work repair mortar and preparation method thereof
The invention discloses magnesium phosphate maritime work repair mortar and a preparation method thereof. The magnesium phosphate maritime work repair mortar is prepared from magnesium oxide, monopotassium phosphate, calcium lactate, an early strength agent, tributyl phosphate, metakaolin, polyethylene glycol fibers, mixed sand and water. The preparation method comprises the following steps: firstly, mixing tributyl phosphate and water, and stirring to obtain a mixed solution; stirring magnesium oxide, monopotassium phosphate, calcium lactate, an early strength agent, metakaolin and polyvinyl alcohol fibers to obtain mixed powder; then adding the mixed powder into the mixed solution, and stirring to obtain a mixture; and finally, adding the mixed sand into the mixture, and stirring to obtain the magnesium phosphate maritime work repair mortar. The magnesium phosphate maritime work repair mortar disclosed by the invention has the advantages that the setting time is more than or equal to 22min, the fluidity is more than or equal to 190mm, the fluidity is good, the strength stability is good, the bonding strength is high, the penetration resistance is excellent, and the magnesium phosphate maritime work repair mortar has a wide prospect in the application of ocean engineering.
本发明公开了一种磷酸镁海工修补砂浆及其制备方法，包括氧化镁、磷酸二氢钾、乳酸钙、早强剂、磷酸三丁酯、偏高岭土、聚乙醇纤维、混合砂及水。制备时先将磷酸三丁酯和水混合，搅拌制得混合液；再将氧化镁、磷酸二氢钾、乳酸钙、早强剂、偏高岭土、聚乙烯醇纤维，搅拌制得混合粉料；随后将混合粉料加入混合溶液中，搅拌制得混合物；最后将混合砂加入混合物中，搅拌制得磷酸镁海工修补砂浆。本发明的磷酸镁海工修补砂浆凝结时间≥22min、流动度≥190mm，流动性好，且强度稳定性好、粘结强度高、抗渗透性能优异，在海洋工程的运用中具有广阔的前景。
