The invention discloses an application of a concrete material in a building outer wall, which belongs to the technical field of building materials. The concrete material capable of shortening the final setting time comprises the following three components in parts by weight: 90-100 parts of cement, 5-10 parts of starch and 200-250 parts of sand, wherein the cement and the starch are uniformly mixed with water and then dried by a vacuum freeze-drying process for use. The plasticity in the initial setting period is fully utilized; a mixture is mixed with starch and the mixture is stirred with water; after the active part of the cement is excited, a vacuum freeze-drying process is carried out, the vacuum freeze-drying process is used for maintaining the activity, after ice crystals are sublimated and dried, a large number of fine gaps are generated, a grey white honeycomb-shaped thin and brittle block structure is formed, and the structure lays a good foundation for crushing to the micronfineness due to the fact that the moisture content is small and the structure is bulky.
本发明公开了一种混凝土材料在建筑外墙的应用，属于建筑材料技术领域。本发明的一种缩短终凝时间的混凝土材料，包括水泥、淀粉和砂，三组分重量份数为：水泥90份～100份，淀粉5份～10份，砂200～250份；其中：水泥和淀粉用水混合均匀后，用真空冷冻干燥工艺进行干燥后使用。本发明充分利用初凝期的可塑性，将其与淀粉混合并和水搅拌后，将水泥活性部分激发后，然后进行真空冷冻干燥工艺，而真空冷冻干燥的作用是保持该活性，冰晶升华干燥后，产生大量的细小空隙，形成灰白色蜂窝状薄脆块的结构，该结构由于水分含量小且膨松，为破碎至微米的细度打下良好的基础。
