Negative carbon aggregate prepared by combining alkali excitation and carbonization and method thereof
The invention relates to the technical field of carbon mineralization materials and products, in particular to a negative carbon aggregate prepared through combination of alkali excitation and carbonization and a preparation method of the negative carbon aggregate. The negative carbon aggregate comprises a carbonized cementing material, an alkali-activated material and an auxiliary cementing material, the alkali-activated material accounts for 3%-7% of the mass of the carbonized cementing material, and the auxiliary cementing material accounts for 5%-15% of the mass of the carbonized cementing material. The preparation method comprises the following steps: fully stirring and mixing a carbonized cementing material, an alkali-activated material, an auxiliary cementing material and water to obtain mixed slurry, molding the mixed slurry, and carrying out natural curing and carbonization treatment to prepare the negative carbon aggregate. And the strength of the product is obviously improved by adjusting the ratio of the cementing material.
本发明涉及碳矿化材料及制品技术领域，具体涉及一种碱激发与碳化联用制备的负碳骨料及其方法。所述负碳骨料包括碳化胶凝材料、碱激发材料、辅助胶凝材料，且碱激发材料为占碳化胶凝材料质量份数的3％‑7％，辅助胶凝材料为占碳化胶凝材料质量份数的5％‑15％。将碳化胶凝材料、碱激发材料、辅助胶凝材料与水进行充分搅拌混合得到混合浆体，成型后，经自然养护、碳化处理制备负碳骨料，与现有技术相比，本发明提供的制备方法经激发剂、碳化胶凝材料与其他辅助胶凝材料之间相互辅助，通过调整胶凝材料的配比，明显改善制品的强度。
