Portland cement carbonization early strength agent with negative carbon function as well as preparation method and application thereof
The invention discloses a Portland cement carbonization early strength agent with a negative carbon function as well as a preparation method and application of the Portland cement carbonization early strength agent. The early strength agent comprises the following components in parts by weight: 0-8 parts of Ca2SiO4-alpha 'L powder, 0-5 parts of Ca3Al2O6-o powder and 0-5 parts of CaO powder, the Ca2SiO4-alpha' L powder and the Ca3Al2O6-o powder are respectively obtained by doping Ca2SiO4 and Ca3Al2O6 with K < + >, and the chemical formula of the Ca2SiO4-alpha 'L powder and the chemical formula of the Ca3Al2O6-o powder are respectively K2O. 23CaO. 12SiO2 and K2O. 8CaO. 3Al2O3. The preparation method comprises the following steps: uniformly mixing the Ca2SiO4-alpha 'L powder, the Ca3Al2O3-o powder, the CaO powder and an anhydrous solvent to form slurry, and drying to obtain the early strength agent. The early strength agent provided by the invention not only can effectively solve the problems of high pollution, high price and poor long-term effect in the prior art, but also can enable cement to adsorb CO2 in air, and has a certain carbon capture function.
本发明公开一种具有负碳功能的硅酸盐水泥碳化早强剂及其制备方法和应用。所述早强剂包括如下组分:Ca2SiO4‑α’L粉末0~8重量份、Ca3Al2O6‑o粉末0~5重量份、CaO粉末0~5重量份,其中:所述Ca2SiO4‑α’L、Ca3Al2O6‑o分别为通过K+掺杂Ca2SiO4、Ca3Al2O6得到,其化学式分别为K2O·23CaO·12SiO2与K2O·8CaO·3Al2O3。所述制备方法包括如下步骤:将所述Ca2SiO4‑α’L粉末、Ca3Al2O6‑o粉末、CaO粉末与无水溶剂混合均匀形成浆料,烘干后即得所述早强剂。本发明的所述早强剂不仅能够有效解决现有技术存在污染高、价格昂贵以及长龄期效果差的问题的同时,还可以使水泥吸附空气中的CO2,兼具一定的碳捕集功能。
