Tuff grinding aid, tuff powder adopting same and low-carbon multi-component cementing material
The invention discloses a tuff grinding aid, tuff powder adopting the tuff grinding aid and a low-carbon multi-component cementing material. The low-carbon multi-component cementing material comprises low-heat Portland cement, tuff powder, active silicon dioxide powder, a naphthalene water reducer and a chloride-free salt compound, the tuff powder is obtained by mixing and grinding tuff and a tuff grinding aid to certain fineness, and the tuff grinding aid is composed of triethanolamine, lignin, triisopropanolamine, ethylene glycol and water. The chloride-free salt compound is a mixture of nitrate and nitrite. Compared with the existing cementing material, the cementing material disclosed by the invention has the characteristics of low cement consumption, low hydration heat release, low cost, low energy consumption and less CO2 emission, and has the advantages of optimizing the working performance of freshly mixed concrete, improving the strength development and frost resistance of the concrete, reducing adiabatic temperature rise and avoiding temperature cracks when being applied to the concrete.
本发明公开了一种凝灰岩助磨剂、采用其的凝灰岩粉及低碳多元胶凝材料。本发明所述低碳多元胶凝材料包括低热硅酸盐水泥、凝灰岩粉、活性二氧化硅粉、萘系减水剂及无氯盐化合物，其中凝灰岩粉由凝灰岩与凝灰岩助磨剂混合研磨至一定细度得到，凝灰岩助磨剂由三乙醇胺、木质素、三异丙醇胺、乙二醇及水组成，无氯盐化合物为硝酸盐和亚硝酸盐的混合物。与现有的胶凝材料相比，本发明具有低水泥用量、低的水化放热量、低成本、低能耗、CO2排放量更少的特点，同时应用到混凝土中，可以优化新拌混凝土的工作性能，并提高混凝土的强度发展、抗冻性能，降低绝热温升，避免温度裂缝产生的优点。
