Tuff-based green ecological concrete and preparation method thereof
The invention discloses tuff-based green ecological concrete and a preparation method thereof. The tuff-based green ecological concrete is prepared from the following components in parts by weight: 100 to 140 parts of tuff powder, 30 to 50 parts of tuff particles, 80 to 120 parts of fly ash, 60 to 80 parts of kaolin, 30 to 50 parts of a composite additive, 280 to 350 parts of desert sand, 80 to 120 parts of high-performance hollow glass beads, 100 to 150 parts of ceramsite and 160 to 200 parts of water, wherein the composite additive is prepared by taking monopotassium phosphate, sodium dihydrogen phosphate, carbamide and graphene oxide dispersion liquid as main raw materials and conducting fermentation and compounding. The obtained ecological concrete has good water retention, fertilizer fixation, air permeability and durability, can be used for desert edge windbreak forests, gobi planting plants, wind prevention and sand fixation, can realize resource utilization of tuff, desert sand and the like, and produces important economic and environmental benefits.
本发明公开了一种凝灰岩基绿色生态混凝土及其制备方法，各组分及其所占重量份数包括：凝灰岩粉100～140份，凝灰岩颗粒30～50份，粉煤灰80～120份，高岭土60～80份，复合外加剂30～50份，沙漠砂280～350份，高性能空心玻璃微珠80～120份，陶粒100～150份，水160～200份；其中所述复合外加剂以磷酸二氢钾、磷酸二氢钠、碳酰胺和氧化石墨烯分散液为主要原料，经发酵复配而成。本发明所得生态混凝土具有良好保水、固肥、透气性能和耐久性能，可用于沙漠边缘防风林、戈壁种植植物、防风固沙，并可实现凝灰岩、沙漠砂等资源化利用，具有重要的经济和环境效益。
