Basic magnesium sulfate cement coral concrete for island reef engineering and preparation process of basic magnesium sulfate cement coral concrete
The invention discloses island reef engineering basic magnesium sulfate cement coral concrete and a preparation process thereof, and belongs to the technical field of constructional engineering materials, the concrete formula comprises the following components in parts by mass: 560-1085 parts of a cementing material, 380-1060 parts of coral sand fine aggregate, 163-454 parts of coral coarse aggregate, 186-307 parts of mixing water and 11-28 parts of a naphthalene-based superplasticizer; the cementing material is prepared from light calcined magnesia, magnesium sulfate pentahydrate, an additive and an active mineral admixture, and the active mineral admixture is a mixture of coral micropowder and granulated blast furnace slag micropowder or fly ash. The invention has the advantages of effective reduction of construction cost and engineering period, rapid hardening, early strength, good mechanical properties, low steel bar corrosion rate, zero expansion, zero shrinkage, difficult cracking and the like.
本发明公开了一种岛礁工程碱式硫酸镁水泥珊瑚混凝土及其制备工艺，属于建筑工程材料技术领域，混凝土配方按质量份数包括：胶凝材料560～1085份、珊瑚砂细骨料380～1060份、珊瑚粗骨料163～454份、拌合用水186～307份和萘系高效减水剂11～28份；所述胶凝材料由轻烧氧化镁、五水硫酸镁、外加剂和活性矿物掺合料制成，活性矿物掺合料为珊瑚微粉与粒化高炉矿渣微粉或粉煤灰的混合物。本发明具有有效缩减施工成本和工程周期、快硬早强、力学性能好、钢筋腐蚀速率低、零膨胀零收缩、不容易开裂等优点。
