Lake and reservoir sediment autoclaved baking-free brick and preparation method thereof
The present invention relates to a lake and reservoir sediment autoclaved baking-free brick mix proportion and a preparation method thereof, the autoclaved baking-free brick comprises the following raw materials by weight: 48-72% of deposited sediment, 8-12% of quick lime, 8-20% of fly ash, 0-10% of slag, and 8-15% of water. The preparation method of the autoclaved baking-free brick comprises the following steps: 1) weighing and uniformly mixing; 2) standing and digesting: adding water in the raw materials twice, adding 70% of water into the mixture A for the first time, standing and digesting for 4-8 hours, adding the rest of water, and stirring to obtain a mixture B; (3) compression molding: putting the mixture B into a mold, and pressurizing the mold by using a press machine so that the mixture B is subjected to compression molding to obtain a green brick; the forming pressure is 600kN; the moisture content of the green brick is 5-8%; and 4) autoclaved curing: standing the green brick at normal temperature for 4-8 hours, and performing autoclaved curing in an autoclave for 5-8 hours at the autoclaved curing temperature of 180 DEG C and the autoclaved pressure of 1 MPa.
本发明涉及一种湖库泥沙蒸压免烧砖配合比及制备方法，按重量百分比计，蒸压免烧砖的原料组成为：淤积泥沙48～72％、生石灰8～12％、粉煤灰8～20％、矿渣0～10％、水8‑15％。该蒸压免烧砖的制备方法，包括：1)称量混匀；2)静置消化：分两次加入原料组成中的水，第一次向混合料A中加入70％的水，静置消化4～8h后，加入剩余的水进行搅拌，得混合料B；3)压制成型：将混合料B置于模具中，使用压力机对模具加压使混合料B压制成型，得砖坯；成型压力600kN；砖坯的含水率5％～8％；4)蒸压养护：将砖坯常温静置4～8h，在蒸压釜中进行蒸压养护5～8h，蒸压养护的温度为180℃，蒸压压力1MPa。
