Biomass carbon self-sensing cement material as well as preparation method and application thereof
The invention provides a biomass carbon self-sensing cement material as well as a preparation method and application thereof, and particularly relates to the technical field of cement materials. The biomass carbon self-sensing cement material provided by the invention is prepared from the following components in parts by mass: 85 to 95 parts of cement, 0.3 to 0.9 part of biomass carbon, 0.5 to 1.5 parts of a water reducing agent and 32 to 50 parts of water, the preparation method of the biomass carbon comprises the following steps: mixing biomass with a polyol solution, carrying out solid-liquid separation, carrying out steam explosion on the obtained solid, and carrying out alkaline leaching on the obtained explosion product to obtain biomass cellulose; carbonizing the biomass cellulose to obtain carbonized cellulose; and carrying out alkali activation on the carbonized cellulose to obtain the biomass carbon. The biomass carbon obtained by the invention can improve the conductivity of the cement material, and has good hydrophilicity; and the water reducing agent can improve the fluidity of the material and improve the crack resistance and early strength of the cement material.
本发明提供了一种生物质碳自感知水泥材料及其制备方法和应用，具体涉及水泥材料技术领域。本发明提供的生物质碳自感知水泥材料，以质量份数计，包括以下组分：水泥85～95份，生物质碳0.3～0.9份，减水剂0.5～1.5份和水32～50份；所述生物质碳的制备方法包括以下步骤：将生物质与多元醇溶液混合，固液分离，将所得固体进行蒸汽爆破，将所得爆破产物进行碱浸，得到生物质纤维素；将所述生物质纤维素进行碳化，得到碳化纤维素；将所述碳化纤维素进行碱活化，得到所述生物质碳。本发明得到的生物质碳可提高水泥材料的电导率，同时具有良好的亲水性；减水剂可提高材料的流动性，改善水泥材料的抗裂性能和早期强度。
