All-solid waste negative carbon concrete and preparation method thereof
The invention provides all-solid waste negative carbon concrete and a preparation method thereof. The preparation method comprises the following steps: 1) weighing 360-400 parts by weight of a cement-free cementing material, 1000-1100 parts by weight of recycled coarse aggregate, 700-800 parts by weight of recycled fine aggregate, 3-5 parts by weight of a water reducing agent and 160-180 parts by weight of water; (2) mixing and forming the materials through a concrete mixer; and 3) carrying out pre-curing and carbon dioxide curing on the molded product to obtain the all-solid waste negative carbon concrete. The raw materials involved in the invention are all solid wastes, carbon emission is extremely low, carbon sequestration is further performed through carbon dioxide curing, and carbon dioxide absorbed in the carbon sequestration stage is greater than carbon emission in the raw materials and the production process, so that the total carbon emission of the concrete is negative.
本发明提供了一种全固废负碳混凝土及其制备方法，包括以下步骤：1)按照重量份计称取无水泥胶凝材料360‑400份、再生粗骨料1000‑1100份、再生细骨料700‑800份、减水剂3～5份和水160～180份；2)将上述材料通过混凝土搅拌机拌和、成型；3)将成型好的产品通过预养护和二氧化碳养护得到全固废负碳混凝土。本发明涉及的原材料全部为固体废物，碳排放量极低，并通过二氧化碳养护进一步固碳，固碳阶段吸收的二氧化碳大于原材料和生产过程碳排放，实现混凝土总碳排为负。
