Biochar-based impermeable cement mortar and preparation method thereof
The invention provides biochar-based impermeable cement mortar and a preparation method thereof, and relates to the technical field of building materials. The impermeable cement mortar is prepared from the following raw materials: 1 part of cement, 3 parts of sand and 0.5 part of water, the cement contains 1 to 5 weight percent of biochar. According to the method, plant straw, tobacco leaves and wood are treated in a pyrolysis carbonization mode, and greenhouse gas is not additionally discharged outwards in the production process; the prepared biochar is an efficient carbon sequestration material, the biochar-based negative carbon cement is prepared by adding the biochar into a cement material, and the biochar-based negative carbon cement is applied to engineering, so that carbon neutralization in the building industry can be realized in an assisted manner. And the porous biochar has a huge specific surface area, provides cement hydration nucleation sites, accelerates cement hydration, improves the cement hydration degree, further improves the compactness of hardened cement paste, and improves the strength and anti-seepage performance, so that the porous biochar can be used for improving the anti-seepage performance of traditional cement.
本申请提出了一种生物炭基防渗水泥胶砂及其制备方法，涉及建筑材料技术领域。该防渗水泥胶砂的原料包括1份水泥、3份砂和0.5份水；所述水泥中含有1‑5wt％的生物炭。本申请采用热解炭化的方式对植物秸秆、烟叶和木材进行处理，在生产过程中不额外向外排放温室气体；制备得到的生物炭是一种高效固碳的材料，将其加入至水泥材料中制备成一种生物炭基负碳水泥，并将之应用于工程中，可助力实现建筑行业“碳中和”。并且该多孔生物炭具有巨大的比表面积，提供了水泥水化成核位点，加速水泥水化，提高了水泥水化程度，进而提高了硬化水泥浆体密实度，其强度与防渗性能也随之提高，因此可用于提高传统水泥的抗渗性能。
