Sludge-based baking-free brick and preparation method thereof
The invention discloses a sludge-based baking-free brick and a preparation method thereof, and belongs to the technical field of baking-free brick preparation, sludge, coal gangue, straw, calcium hydroxide and water are used as raw materials to prepare the sludge-based baking-free brick, the sludge is used as a main material to play roles of bonding and structural aggregate; after being activated by microwaves, the coal gangue can react with calcium hydroxide to generate a gelling product; the calcium hydroxide mainly plays a role in exciting the activity of the coal gangue and the sludge and carbonizing a reaction calcium source; the straw fibers have the effects of avoiding shrinkage cracking and enhancing the breaking strength. The performance indexes of the steaming-free and pressing-free sludge-based baking-free brick prepared by the preparation method provided by the invention meet and are superior to the MU7.5-grade standard in the industrial standard JC 422-1991 Non-Sintered Common Clay Bricks.
本发明公开了一种淤泥基免烧砖及其制备方法，属于免烧砖制备技术领域，本发明以淤泥、煤矸石、秸秆、氢氧化钙和水为原料制备得到淤泥基免烧砖，其中，淤泥作为主要材料起到粘结、结构骨料的作用；煤矸石经微波活化后能够与氢氧化钙反应生成胶凝产物；氢氧化钙主要起到激发煤矸石和淤泥活性以及碳化反应钙源的作用；秸秆纤维起到避免收缩开裂以及增强抗折强度的作用。本发明制备的免蒸免压淤泥基免烧砖的性能指标满足并优于行业标准JC 422‑1991《非烧结普通粘土砖》中的MU7.5级标准。
