Biochar cement and preparation method thereof
The invention provides charcoal cement and a preparation method thereof, and relates to the technical field of building materials. The biochar cement is prepared from the following raw materials: cement and a cement additive, and the cement additive is prepared from biochar and cellulose; the addition amount of the charcoal is 1-10% of the mass fraction of the cement; the addition amount of the cellulose is 0.5% of the mass fraction of the cement. The charcoal is added into the cement for partial replacement, so that the use amount of the cement can be reduced under the condition of conforming to related national standards, and the carbon emission is further reduced. In the subsequent use process of the cement, the charcoal cement can absorb and convert carbon dioxide in air by utilizing charcoal, so that carbon reduction is realized. Biochar is prepared from straw, natural carbon removal is inhibited, carbon is solidified in cement, and carbon sequestration is achieved.
本申请提出了一种生物炭水泥及其制备方法，涉及建筑材料技术领域。一种生物炭水泥，所述生物炭水泥的原料包括水泥和水泥添加剂，所述水泥添加剂包括生物炭和纤维素；所述生物炭的添加量为水泥质量分数的1‑10％；所述纤维素的添加量为水泥质量分数的0.5％。本申请在水泥中加入生物炭部分替代，在符合相关国标的情况下可以降低水泥的用量，进而降低碳排。在水泥的后续使用过程中，生物炭水泥可以利用生物炭吸收并转化空气中的二氧化碳，实现减碳。采用秸秆制生物炭，抑制天然的碳移除并将碳固化在水泥中，实现碳封存。
