The invention discloses a magnesium oxide-based masonry and a preparation method thereof, and relates to the technical field of civil engineering building materials, the magnesium oxide-based masonry comprises the following raw materials: 1 part of light calcined magnesia cement, 1 part of fly ash and 3 parts of coarse aggregate, the water-cement ratio in the preparation process is 0.45, and after the raw materials are mixed to prepare the masonry, the masonry can be used as a building material. And carrying out carbonization maintenance for not less than 28 days to obtain the magnesium oxide-based masonry. According to the invention, the ratio of the light calcined magnesia cement to the fly ash to the coarse aggregate is redesigned, and carbonization maintenance is carried out for not less than 28 days, so that the light calcined magnesia cement can completely replace Portland cement to prepare the masonry under the condition of ensuring the durability.
本发明公开了一种氧化镁基砌体及其制备方法，涉及土木工程建筑材料技术领域，所述氧化镁基砌体的原料配比为：轻烧氧化镁水泥1份、粉煤灰1份、粗骨料3份，制备过程中水灰比为0.45，原料混合制成砌体后，进行不低于28天的碳化养护即可得到所述氧化镁基砌体。本发明通过重新设计轻烧氧化镁水泥、粉煤灰、粗骨料的配比，并通过不低于28天的碳化养护，在保证耐久性的情况下，能够使得轻烧氧化镁水泥完全替代硅酸盐水泥，制备砌体。
