免烧免蒸建筑用砖
摘要：
一种免烧免蒸建筑用砖，属建筑用砖技术领域。所要解决的技术问题是提供原料来源广泛、成本低的免烧免蒸建筑用砖，以扩大自然养护类建筑用砖的种类和生产规模。技术方案是，它由主料和作为胶凝剂的辅料组成，其原料为(重量份)：主料为石渣或矿渣，含量80－85，胶凝剂为黄板子石粉和生石灰，其中黄板子石粉的含量为7－10、生石灰的含量为6－13，石渣或矿渣的粒度≤φ8mm，黄板子石粉的粒度≥85目。经压力成型、自然养护形成水化硅酸盐钙，还原成托贝莫来石晶体。本发明用黄板子石粉加上生石灰可完全取代水泥，无须加入水泥，便可获得类似水泥混凝土砖类的制品。原料来源广泛，成本低廉，易于获取，有利于扩大生产规模、保护环境。
摘要（英）：

The present invention relates to a baking-free and steaming-free brick. It is formed from main material and auxiliary material as gelatinizing agent, the main material is stone ballast and slag, its content is 80-85 weight portions, and the gelatinizing agent is huangbanzi stone powder and quicklime, in which the huanbanzi stone powder content is 7-10 portions and the quicklime content is 6-13 portions, gran size of ballast or slag is less than or equal to 8mm, and the grain size of huangbanzi stone powder is greater than or equal to 85 meshes. Said invention adopts the processes of pressure forming and natural curing to form hydrated calcium silicate and reducing it to obtain tobermorite crystal. Said invention can use the huangbanzi stone powder and quicklime instead of cement to obtainthe product similar to cement concrete brick.
