Carbonization-cured high-strength coal gangue-based low-carbon baking-free grass planting brick and preparation method thereof

The invention relates to a carbonized and cured high-strength coal gangue-based low-carbon unfired grass planting brick and a preparation method thereof. The carbonized and cured high-strength coal gangue-based low-carbon unfired grass planting brick is prepared from the following raw materials in parts by weight: 260 to 520 parts of coal gangue-based geopolymer, 624 to 936 parts of coal gangue fine aggregate, 1144 to 1714 parts of slurry-coated coal gangue coarse aggregate and 200 to 300 parts of water. Through the synergistic effect of all the raw material components, the prepared carbonized and cured high-strength coal gangue-based low-carbon unfired grass planting brick is high in strength, good in durability such as freezing resistance, weather resistance, carbonization resistance and water resistance, high in coal gangue utilization rate, low in carbon emission, good in plant adaptability and good in environmental coordination, and conforms to the concepts of circular economy and ...
