Baking-free brick as well as preparation method and application thereof
The invention belongs to the technical field of building materials, and discloses a baking-free brick and a preparation method and application thereof, the baking-free brick comprises the following components by weight: cement, gravel powder, river sand, fly ash and water; the ratio of the cement to the gravel powder to the river sand to the fly ash to the water is 1: 2.4: 0.4: 0.4: 1; the particle size of the crushed stone powder is less than or equal to 3mm, and the silt content is less than or equal to 3%; the grain size of the river sand is less than or equal to 5mm, and the silt content is less than or equal to 3%; weighing the materials, putting the crushed stone powder, the river sand, the fly ash and the cement into a mixing mill, adding water, and uniformly mixing and milling; and conveying the materials mixed and ground by the mixing and grinding machine into a mold, pressing the materials into building blocks with the length of 240mm, the width of 115mm and the height of 53mm by a brick press, and naturally drying the building blocks. The manufacturing process is simple, a sintering procedure is omitted, a large amount of carbon dioxide generated by sintering is avoided, and environmental pollution is avoided; the brick press is small in machine weight, flexible in carrying and capable of being directly installed and produced on a construction site, and damage caused by repeated carrying of bricks is reduced.
本发明属于建筑用材料技术领域，公开了一种免烧砖及其制备方法和应用，按如下重量份数由水泥、碎石粉、河沙、粉煤灰和水组成；水泥：碎石粉：河沙：粉煤灰：水＝1：2.4：0.4：0.4：1；所述碎石粉的粒径≤3mm，含泥量≤3％；所述河沙的粒径≤5mm，含泥量≤3％；称料，将碎石粉、河沙、粉煤灰和水泥置于混碾机内加入水混碾均匀；将经混碾机混碾后的物料输送至模具中由压砖机压制成长240mm，宽115mm，高53mm的砌块，将砌块自然干燥。本发明制作工艺简单，没有烧结工序，避免了因烧结而产生的大量二氧化碳，没有环境污染；压砖机体量小、搬运灵活，可直接在施工现场安装生产，减少砖砌多次搬运造成的破损。
