Functional carbon-reducing auxiliary agent for reducing carbon emission of concrete and preparation method of functional carbon-reducing auxiliary agent
The invention discloses a functional carbon-reducing auxiliary agent for reducing carbon emission of concrete and a preparation method of the functional carbon-reducing auxiliary agent. The auxiliary agent is prepared from the following raw materials in parts by weight: 10-40 parts of ethyl orthosilicate, 10-40 parts of tetra calcium aluminoferrite, 8-16 parts of a water reducing agent, 5-20 parts of an air entraining agent, 5-20 parts of a reinforcing agent and 20-50 parts of an adhesive. Tetraethoxysilane and tetracalcium aluminoferrite in the auxiliary agent are combined for use, so that the mechanical property of the concrete prepared by taking the machine-made sand as aggregate can be remarkably enhanced, and synergistic interaction is realized; sodium dodecyl benzene sulfonate and modified rosin powder are used as composite air entraining agents, so that the slump of concrete slurry is improved; and the modified epoxy resin and the modified water glass are used as a composite adhesive, so that the static compressive elastic modulus of the concrete is improved.
本发明公开了一种降低混凝土碳排放的功能性减碳助剂及制备方法。所述助剂由如下重量份数的原料制成：正硅酸乙酯10‑40份、铁铝酸四钙10‑40份、减水剂8‑16份、引气剂5‑20份、增强剂5‑20份、粘接剂20‑50份。本发明的助剂中正硅酸乙酯和铁铝酸四钙的组合使用，能显著增强以机制砂为集料制备的混凝土的力学性能，且协同增效；以十二烷基苯磺酸钠与改性松香粉作为复合引气剂，改善了混凝土浆料的坍落度；以改性环氧树脂与改性水玻璃作为复合粘接剂，改善了混凝土的静力受压弹性模量。
