Method for curing mineralized concrete blocks by using flue gas of coal-fired power plant
The invention discloses a method for curing mineralized concrete blocks by using flue gas of a coal-fired power plant. The problem of how to cure the mineralized concrete blocks by using the flue gas of the coal-fired power plant is solved. Putting the concrete blocks subjected to pre-curing in the second step into a closed mineralization curing axe; flue gas exhausted by the coal-fired power plant is introduced into a closed mineralization maintenance kettle, the CO2 concentration in the flue gas exhausted by the coal-fired power plant is 10-14%, the moisture in the flue gas is 9-13%, the PH value of the flue gas is 5-7, in the closed mineralization maintenance kettle, the air pressure of the introduced CO2 is kept at 0.4-0.8 MPa, and the mineralization maintenance time is 72 hours; the carbon sequestration rate of the concrete block is improved, and the strength of the concrete block is greatly improved.
本发明公开了一种利用燃煤电厂烟气养护矿化混凝土砌块的方法，解决了如何利用燃煤电厂烟气养护矿化混凝土砌块的问题；将完成第二步预养护的混凝土砌块放入密闭的矿化养护斧中；将燃煤电厂排出的烟气通入到密闭的矿化养护斧中，燃煤电厂排出的烟气中的CO2浓度为10‑14%，烟气中的水分为9‑13%，烟气的PH值为5‑7，在密闭的矿化养护斧中，通入的CO2的气压保持在0.4‑0.8兆帕，矿化养护时间为72小时；提高了混凝土砌块的固碳率，大大提高了混凝土砌块的强度。
