Lake and reservoir sludge sintered brick and preparation method thereof
The invention relates to a lake and reservoir sludge sintered brick and a preparation method thereof, and the sintered brick comprises the following raw materials in percentage by weight: 0-30% of shale, 0-30% of coal gangue, 0-10% of coal and 40-100% of lake and reservoir sludge. The preparation method of the lake and reservoir sludge sintered brick comprises the following steps: (1) weighing and uniformly mixing: weighing the raw materials according to the ratio, adding water accounting for 10% of the total mass of the raw materials, and uniformly mixing to obtain a mixture for later use; (2) compression molding: putting the mixture into a mold, and pressurizing the mold by using a press machine to compress and mold the mixture to obtain a green brick; the forming pressure ranges from 400 kN to 600 kN; (3) green brick drying: naturally drying the green brick in a room temperature environment for 72 hours; drying the green brick in a drying oven at 105 DEG C for 3 hours; and (4) roasting the green brick: putting the dried green brick into a muffle furnace, and sintering for 90-120 minutes at the temperature of 850-1050 DEG C, thereby obtaining the product.
本发明涉及一种湖库淤泥烧结砖及制备方法，按重量百分比计，烧结砖的原料组成为：页岩0～30％，煤矸石0～30％，煤炭0～10％，湖库淤泥40～100％。该湖库淤泥烧结砖的制备方法，包括：(1)称量混匀：按配比称取各原料，加入占各原料总质量10％的水，混合均匀，得混合料，备用；(2)压制成型：将混合料置于模具中，使用压力机对模具加压使混合料压制成型，得到砖坯；成型压力为400～600kN；(3)砖坯干燥：将砖坯在室温环境中自然干燥72h；干燥后将砖坯放置于105℃的烘箱中干燥3h；(4)砖坯焙烧：将干燥后的砖坯置于马弗炉中，在850～1050℃温度下烧结90～120min，即得。
