Low-carbon concrete duct piece
The pipe piece comprises a pipe piece body and a reinforcement cage arranged in the pipe piece body, the pipe piece body is made of low-carbon concrete, the low-carbon concrete comprises the following raw materials of a binding material, aggregate, a water reducing agent and water, and the binding material comprises gamma-C2S and cement. A carbonization active cementing material gamma-C2S is added into the low-carbon concrete duct piece, in the service process of the low-carbon concrete duct piece, the gamma-C2S can absorb CO2 for a long time, Ca (OH) 2 in cement and the gamma-C2S generate CaCO3 minerals with CO2, pores of a concrete structure are gradually filled with the minerals, the specific surface area of a concrete material is reduced, and the service life of the low-carbon concrete duct piece is prolonged. Therefore, in the carbonization process, the mechanical property of the concrete structure can be enhanced, harmful ions can be prevented from entering through the compact structure, and the durability of the low-carbon concrete duct piece is improved.
本发明提供了一种包括管片本体和设置在所述管片本体内的钢筋笼，所述管片本体的材料为低碳混凝土，所述低碳混凝土包括以下原料：胶凝材料、骨料、减水剂和水，所述胶凝材料包括γ‑C2S和水泥。本发明低碳混凝土管片在中添加了碳化活性胶凝材料γ‑C2S，在低碳混凝土管片服役的过程中，γ‑C2S能够长期吸收CO2，水泥中的Ca(OH)2和γ‑C2S与CO2生成了CaCO3类的矿物，这些矿物逐渐填充到混凝土结构的孔隙中去，减少混凝土材料的比表面积，因此碳化过程能够增强混凝土结构的力学性能的同时，还能通过致密的结构阻碍有害离子的进入，增加了低碳混凝土管片的耐久性。
