Zusammenfassung:	The invention discloses a preparation method of a light-weight brick. The light-weight brick comprises following raw materials, by mass, 40-60% of fly ash, 20-30% of cement, 5-10% of river sand, 5-10% of wood chip powder and 5-10% of paper pulp. The preparation method includes following steps: fully dry-mixing the raw materials, adding water for wet-mixing the raw materials, ageing the raw materials after the wet-mixing process completed, performing extrusion moulding by pouring the raw materials into a mould, and finally performing a naturally drying process. The light-weight brick is simple in components, is low in cost and is simple in a production and control processes.
