Autoclaved aerated concrete material and preparation method thereof
The invention discloses an autoclaved aerated concrete material and a preparation method thereof, and belongs to the technical field of novel building materials. The graphene oxide loaded calcium carbonate and the graphene oxide are added into the material provided by the invention, nucleation sites generated by the graphene oxide loaded calcium carbonate cause a deep microstructure of the material to directionally generate a fiber-like nanoneedle-shaped multi-stage micro-nano structure, and nanowires are split from tips of the nanoneedle-shaped structure and are filled in capillary pores and microscopic pores, so that the nanowires are uniformly dispersed in the micro-pores and the micro-pores; the appearance of a meniscus is effectively avoided, the compactness is increased, the pressure of capillary pores can be further dispersed by the nanowires, and the pressure difference of the capillary pores is reduced, so that drying shrinkage is avoided. The graphene oxide ions can reduce the gravitation between the colloidal particles and block the distance between the particles, so that drying shrinkage is further avoided. Therefore, the material provided by the invention can effectively solve the cracking problem caused by drying shrinkage, the durability of the material is improved, and the service life of the material is prolonged.
本申请公开了一种蒸压加气混凝土材料及其制备方法，属于新型建筑材料技术领域。本申请提供的材料中添加了氧化石墨烯负载碳酸钙和氧化石墨烯，氧化石墨烯负载碳酸钙产生的成核位点导致材料深层微观结构定向生成类“纤维”纳米针状的多级微纳结构，且纳米针状结构尖端分裂出纳米丝，填充在毛细孔及微观孔中，有效避免了弯月面的出现，并增大了密实度，纳米丝能进一步分散毛细孔压力，降低毛细孔压力差，从而避免干燥收缩。氧化石墨烯离子能够降低胶粒之间的引力，阻隔颗粒之间的距离，从而进一步避免干燥收缩。因此，本申请提供的材料可以有效解决因干燥收缩导致的开裂问题，提高了材料的耐久性和使用寿命。
