From the conclusion, the additive prepared by the invention can effectively improve the depth and degree of carbon mineralization of the product, and ensures that the product has enough compression resistance and bending strength.
According to the invention, the porous material is taken as a framework, and is modified by adopting the solid-liquid phase change material, and the modified porous material can construct a carbon mineralization reaction channel in the prefabricated member, so that moisture and carbon dioxide gas can freely migrate in the carbon mineralization process, and the rapid and uniform reaction of carbon dioxide in the prefabricated member under the low pressure condition is realized, thereby solving the problem of 'inside-outside difference' caused by different carbonization degrees of the prefabricated member.
More importantly, the phase change material introduced by the invention solidifies and plugs pores at normal temperature, avoids the negative influence of high water absorbability of the pores on the working performance of the material, and generates phase change reaction under the thermal condition of carbon mineralization reaction (exothermic reaction), thereby realizing the regulation and control of the pore state of the porous material, and specifically comprises the following steps: in the carbon mineralization process, the phase change material is melted, a channel is opened, free exchange and migration of water and gas are realized, and the defect of internal expansion stress of the material caused by overhigh internal water vapor pressure due to overhigh carbon mineralization reaction speed is avoided; after mineralization reaction is completed, when the temperature is restored to normal temperature, the phase change material is solidified to block the air holes, thereby blocking the corrosion and pollution of harmful impurities in the environment to the inside of the product and improving the durability of the carbonized product. In addition, the product prepared in the example 4 is slightly lower than the products prepared in the examples 1 and 2 in terms of carbon fixation rate and fracture and compression strength, which shows that the microencapsulation mode is more beneficial to playing the role of the additive; the microcapsule packaging mode continuously wraps the surface of the porous material with a film formed by the phase change material, so that the structural performance of the porous material is not damaged in the prefabrication process, the microcapsule form is damaged due to carbonization pressure and flow friction of gas in the carbon mineralization process, and the part of the porous material is exposed, so that the function of constructing a carbon mineralization water-gas channel is achieved.
It should be noted that the phase transition temperature of the solid-liquid phase change material has an important influence on the additive effect, and the solid-liquid phase change material should realize solid-liquid state transition under the reaction heat of the product carbon mineralization process, so as to ensure the opening of the pores of the porous material, and after the reaction is finished and the normal temperature is restored, the solid-liquid phase change material is solidified again to form a solid, so that the pores of the porous material are plugged. Therefore, according to the reaction heat in the carbon mineralization process, the phase change temperature interval of the solid-liquid phase change material is determined to be 35-70 ℃, and when the inventors use the phase change material with the phase change temperature interval of more than 70 ℃ to encapsulate slag, the formed additive is in an equivalent doping amount (the raw materials of the used carbon mineralization product are the same as those of the embodiment 1), and the carbon fixation rate of the obtained product is obviously lower than that of the embodiment 1.
The above-described embodiments of the present invention do not limit the scope of the present invention. Any other corresponding changes and modifications made in accordance with the technical idea of the present invention shall be included in the scope of the claims of the present invention.
