Carbon dioxide (CO₂) emissions from industrial processes contribute largely to the greenhouse effect and climate change. One of these industries is the cement industry, which contributes around 8% of CO₂ emissions caused by mankind. Two promising and interesting ways to reduce CO₂ emission are the utilization of alternative cementitious materials and carbon capture and utilization through CO₂ mineralization. In this study, peat-wood fly ashes from fluidized bed combustion were used as a construction material for mineral carbonation. A self-hardening characteristic of this type of fly ash was utilized, and simultaneous carbonation and hydration reactions were studied. The study showed that fly ashes from the fluidized bed combustion of peat and wood could be used to capture and mineralize CO₂ during hydration reactions. At the same time, CO₂ could improve the strength of self-hardened fly ashes. One interesting future possibility is fly ash tile production at energy plants: fly ashes can be used to capture CO₂ from flue gases, thus improving the strength of produced tiles.

工业过程中的二氧化碳（CO ₂）排放在很大程度上造成了温室效应和气候变化。一个这些行业的是水泥工业，这有助于在8％左右的CO ₂引起的人类排放。减少CO ₂排放的两种有希望且有趣的方法是利用替代性胶结材料以及通过CO _2进行碳捕获和利用矿化。在这项研究中，流化床燃烧产生的泥炭飞灰被用作矿物碳化的建筑材料。利用这种类型的粉煤灰的自硬化特性，并研究了同时发生的碳酸化和水合反应。研究表明，泥炭和木材流化床燃烧产生的飞灰可用于水合反应期间捕获和矿化CO ₂。同时，CO ₂可以提高自硬飞灰的强度。未来一个有趣的可能性是在能源工厂生产粉煤灰瓦：粉煤灰可用于从烟道气中捕集CO ₂，从而提高生产瓦的强度。
