Industrial solid waste carbonization and solidification baking-free building block and preparation method thereof
The invention relates to an industrial solid waste carbonization and solidification baking-free building block and a preparation method thereof, and belongs to the technical field of civil construction engineering materials. The industrial solid waste carbonized and cured baking-free building block is prepared from the following raw materials in parts by mass: 250-400 parts of carbide slag; 250 parts to 400 parts of blast furnace slag; 250 to 350 parts of water; and 50 to 100 parts of CO2. Based on the idea of treating waste with waste, all the raw materials except water are bulk wastes generated in industrial production: the pH value of the carbide slag is about 13, a large amount of CO2 can be absorbed in the carbonization process, and an alkaline environment is provided for active components in the blast furnace slag; main components of the blast furnace slag can be subjected to hydration, pozzolanic reaction and gelling reaction, so that the strength of the building block is better enhanced; by adding CO2, alkaline substances in the building block are converted into carbonate with relatively high strength and volume, so that pores of the building block are filled, and the strength of the building block is further improved.
本发明涉及一种工业固废碳化固化免烧砌块及制备方法，属于土木建筑工程材料技术领域。该工业固废碳化固化免烧砌块的原料的质量份数配合比为：电石渣：250份‑400份；高炉矿渣：250份‑400份；水：250份‑350份；CO2：50份‑100份。本发明基于以废治废的思路，原料除水外全部为工业生产所产生的大宗废物：电石渣的pH值在13左右，在碳化过程中能吸收大量CO2，并为高炉矿渣中的活性成分提供了碱性环境；高炉矿渣的主要成分能够发生水化、火山灰和胶凝反应，较好地增强砌块的强度；CO2的加入使得砌块中的碱性物质转变为强度和体积均较大的碳酸盐，填补了砌块孔隙，使得砌块强度进一步提高。
