Cementing material of ecological concrete and ecological concrete thereof
The invention relates to a cementing material of ecological concrete and the ecological concrete.The cementing material comprises, by weight, 30%-40% of gypsum, 20%-30% of mineral powder, 3%-5% of kieselguhr, 6%-8% of modified zeolite and the balance sulphoaluminate cement. The preparation method comprises the following steps: preparing a chitosan solution with the mass concentration of 20% for later use, and uniformly mixing zeolite powder with SPA for later use; spraying a chitosan solution on the mixture, and then drying to obtain the modified zeolite. According to the cementing material disclosed by the invention, the gypsum, the mineral powder, the diatomite, the modified zeolite and the aluminum sulfate cement are compounded into a plurality of materials, the alkalinity reduction action mechanisms of different materials are different, the respective defects are mutually compensated, a synergistic effect is generated, mutual promotion is realized, and the alkalinity of the concrete is more effectively reduced. Meanwhile, the microstructure and macroscopic performance of the concrete can be improved, and the durability and stability of the concrete are improved.
本发明涉及一种生态混凝土的胶凝材料及其生态混凝土，按照重量百分比计，包括石膏30‑40％、矿粉20‑30％、硅藻土3‑5％、改性沸石6‑8％，余量为硫铝酸盐水泥，所述的改性沸石的制备方法：所述的改性沸石的制备方法：将壳聚糖溶于水，形成质量浓度20％的壳聚糖溶液，备用，将沸石粉与SPA混合均匀，备用；将壳聚糖溶液喷洒在混合物上，然后干燥，即得改性沸石。本发明的胶凝材料采用石膏、矿粉、硅藻土、改性沸石和硫酸铝盐水泥复合多种材料，将不同材料的降碱作用机理不同，相互补偿各自的不足，产生协同效应，相互促进，更有效地降低混凝土的碱性。同时还可以改善混凝土的微观结构和宏观性能，提高其耐久性和稳定性。
