Biochar, preparation method thereof, foam concrete and preparation method of foam concrete
The invention relates to the technical field of concrete, and concretely relates to a biochar, a preparation method thereof, a foam concrete and a preparation method of the foam concrete. The biochar with excellent performance is prepared, and the foam concrete is prepared by taking the biochar and sludge incineration ash as raw materials. The preparation method of the foam concrete comprises the following steps: premixing the ash, cement and biochar to obtain a dry mixture; carrying out wet mixing on the obtained dry mixture and water to obtain a wet mixture; mixing the wet mixture with a water reducing agent to obtain a mixture; mixing the obtained mixture with foam to obtain slurry; and pre-curing and curing the obtained slurry in sequence to obtain the foam concrete. According to the embodiment of the invention, the sludge incineration ash is successfully recycled, so that the sludge incineration ash is recycled, and the fixation of the carbon element is realized. The obtained concrete is uniform in pore size distribution, and the physical properties including compression resistance, fracture resistance, dry density, water resistance, heat conductivity coefficient and the like all meet the building industry standard foam concrete (JG/T 266-2011).
本发明涉及混凝土技术领域，尤其涉及一种生物炭及其制备方法和一种泡沫混凝土及其制备方法。本发明制备得到一种性能优异的生物炭，再以生物炭和污泥焚烧灰渣为原料制备得到泡沫混凝土：将灰渣、水泥和生物炭进行预混，得到干混料；将所得干混料和水进行湿混，得到湿混料；将所得湿混料和减水剂混合，得到混合料；将所得混合料和泡沫混合，得到浆料；对所得浆料顺次进行预养护和养护，得到所述泡沫混凝土。由实施例可得，本发明成功回收利用了污泥焚烧灰渣，使其资源化，实现了碳元素的固定。所得混凝土孔径分布均匀，物理性能包括抗压、抗折、干密度、耐水性、导热系数等均符合建筑行业标准《泡沫混凝土》(JG/T 266‑2011)。
