Zusammenfassung:The invention discloses an all-solid-waste building material with boric sludge as a main raw material and a preparation method thereof. The preparation method comprises the following steps: (1) boric sludge pretreatment: drying the boric sludge, crushing and sieving with a 10-mesh sieve; (2) activating the activity of magnesium oxide in the boric sludge; (3) acidifying the boric sludge to prepare acidified boric sludge containing magnesium sulfate; and (4) preparing the boron mud full-solid waste building material to obtain finished products of the boron mud building material, such as baking-free bricks, building blocks, plates and the like, wherein the finished products can also be used for preparing other handicrafts. The method effectively solves the problem of boron mud treatment, is simple to operate and large in boron mud use amount, reduces the production cost of the magnesium oxysulfate cement, saves the cost of boron mud and waste acid treatment, and can obtain good economic benefits and ecological b
