Biochar concrete and preparation method thereof
The invention provides charcoal concrete and a preparation method thereof, and relates to the technical field of building materials. The biochar concrete comprises the following raw materials: cement, coal ash, coarse aggregate, fine aggregate, an additive and water, wherein the cement contains 1-10wt% of biochar. According to the method, tobacco leaves and wood are treated in a pyrolysis carbonization mode, and compared with a traditional method for preparing biochar through combustion, greenhouse gas is not additionally discharged outwards in the production process of the technology; the prepared biochar is an efficient carbon sequestration material, the biochar concrete is prepared by adding the biochar into a cement material, and the biochar concrete is applied to constructional engineering, so that carbon neutralization in the construction industry can be realized in an assisted manner. A certain amount of biochar is loaded in the biochar concrete, and experiments show that the biochar concrete can improve the compressive strength of the concrete and has a certain early strength effect on the concrete.
本申请提出了一种生物炭混凝土及其制备方法，涉及建筑材料技术领域。所述生物炭混凝土的原料包括水泥、煤灰、粗骨料、细骨料、外加剂和水，所述水泥中含有1‑10wt％的生物炭。本申请采用热解炭化的方式对烟叶和木材进行处理，相比于传统的燃烧制备生物炭，本申请工艺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混凝土，并将之应用于建筑工程中，可助力实现建筑行业碳中和。本申请生物炭混凝土中负载一定量生物炭，经过实验表明其对混凝土的抗压强度有所提升，并且对混凝土能起到一定早强作用。
