Self-sensing spraying high-performance glass aggregate concrete and preparation method thereof
The invention discloses self-sensing spraying high-performance glass aggregate concrete and a preparation method thereof, and belongs to the technical field of concrete. The self-sensing jet high-performance glass aggregate concrete is prepared from the following raw materials in parts by mass: 749 to 763 parts of cement, 154 to 170 parts of fly ash, 154 to 170 parts of silica fume, 115 to 125 parts of metakaolin, 840 parts of fine aggregate, 225 to 255 parts of water, 14.6 to 19.0 parts of a water reducing agent and 8.75 to 15.75 parts of carbon fibers, the fine aggregate is composed of glass sand and machine-made sand. According to the prepared high-performance sprayed concrete, glass sand is used for replacing part of machine-made sand, the problems that traditional sprayed concrete is low in strength, insufficient in durability and the like are solved, meanwhile, the capacity of conducting real-time health monitoring on a shaped concrete structure is achieved, the reliability and safety of the structure are guaranteed, the service life is prolonged, and the maintenance cost is reduced.
本发明公开了一种自感知喷射高性能玻璃骨料混凝土及其制备方法，属于混凝土技术领域。所述自感知喷射高性能玻璃骨料混凝土的原料按质量份数计，包括：水泥749～763份、粉煤灰154～170份、硅灰154～170份、偏高岭土115～125份、细骨料840份、水225～255份、减水剂14.6～19.0份和碳纤维8.75～15.75份；所述细骨料由玻璃砂和机制砂构成。本发明制备的高性能喷射混凝土使用玻璃砂代替部分机制砂，解决了传统喷射混凝土的强度低、耐久性不足等问题，同时还具备对定型后的混凝土结构进行实时健康监测的能力，以保障结构的可靠性与安全性，延长使用寿命，降低维护成本。
