Preparation method of environment-friendly carbon sequestration aerated building block
The invention discloses a preparation method of an environment-friendly carbon-sequestration aerated building block, which comprises the following steps of: roasting and activating graphite tailings at low temperature, standing and cooling to room temperature, adding lime, cement, gypsum, the activated graphite tailings and water into a mixing stirrer according to a certain ratio, fully stirring to obtain mixed slurry, pouring the mixed slurry into an aerated building block mold cavity, and carrying out heat preservation and heat preservation to obtain the environment-friendly carbon-sequestration aerated building block. Standing the mold cavity for a period of time to obtain an aerated building block after initial setting, after the building block is demolded, conveying the aerated building block to autoclaved curing equipment, introducing CO2 gas and low-pressure steam during curing to carry out steam curing on a building block green body, and after a period of time, obtaining the environment-friendly carbon sequestration aerated building block. The compressive strength and freezing resistance of the aerated building block are improved, fixation and emission reduction of CO2 gas are realized, use of water vapor is reduced, energy consumption is reduced, meanwhile, a proper path is provided for reduction and resourceful treatment of the graphite tailings, and economical efficiency and practicability are high.
本发明公开了一种环保固碳加气砌块的制备方法，将石墨尾矿进行低温焙烧活化后，放置冷却至室温，将石灰、水泥、石膏、活化后的石墨尾矿和水按计量加入混合搅拌器中充分搅拌，得到混合料浆，将混合料浆浇筑到加气砌块模腔中，将模腔静置一段时间，得到初凝后的加气砌块，待砌块脱模后，送至蒸压养护设备，在养护中通入CO2气体和低压蒸汽对砌块坯体进行蒸汽养护，一段时间后得到环保固碳加气砌块。本发明不仅提高了加气砌块的抗压强度和抗冻性，实现了CO2气体的固定与减排，减少了水蒸气的使用，降低了能耗，同时为石墨尾矿的减量化、资源化处理提供了适宜的路径，经济性和实用性较强。
