Treatment method for recycling aerated concrete high-temperature circulating water
The invention discloses a treatment method for recycling aerated concrete high-temperature circulating water, the high-temperature circulating water is applied to preparation of aerated concrete, and the aerated concrete comprises fly ash, tailing sand, cement, lime, gypsum, magnesium aluminum silicate, waste slurry, high-temperature circulating water, aluminum powder and sodium bicarbonate. During preparation, the fly ash and the tailing sand are ground to prepare a mixture, then the high-temperature circulating water and the waste slurry are mixed to prepare a mixed solution, the cement, the gypsum, the lime, the magnesium aluminum silicate and the mixture are mixed and stirred, then the aluminum powder, the sodium bicarbonate and the mixed solution are added and stirred, aerated concrete slurry is prepared, finally, the slurry is subjected to pouring forming and gas forming, then standing and cutting are conducted, and the aerated concrete is obtained. And performing steam curing to obtain the aerated concrete. The compressive strength of the aerated concrete prepared based on the high-temperature circulating water can reach about 4.0 MPa, the heat conductivity coefficient is smaller than 0.1 W/(m.K), the dry density is smaller than 503 kg/m < 3 >, and the aerated concrete has excellent mechanical properties.
本发明公开了一种加气混凝土高温循环水再利用的处理方法，该高温循环水应用于加气混凝土的制备，该加气混凝土包括粉煤灰、尾矿砂、水泥、石灰、石膏、硅酸镁铝、废浆、高温循环水、铝粉、碳酸氢钠；制备时先将粉煤灰和尾矿砂粉磨制得混合物，然后将高温循环水和废浆混合，制得混合液，将水泥、石膏、石灰、硅酸镁铝和混合物先混合搅拌，再加入铝粉、碳酸氢钠和混合液后搅拌，制得加气混凝土料浆最后将料浆浇筑成型，发气后，再静停、切割，并蒸汽养护制得加气混凝土。本发明基于高温循环水制备的加气混凝土的抗压强度能够达到4.0MPa左右，且导热系数小于0.1W/(m·K)，干密度小于503kg/m3，具有优异的力学性能。
