Porous reticular aggregate/carbon fiber composite modified high-temperature-resistant and high-strength concrete
The invention provides porous reticular aggregate/carbon fiber composite modified high-temperature-resistant high-strength concrete. The porous reticular aggregate/carbon fiber composite modified high-temperature-resistant high-strength concrete comprises the following components: 300-400 parts of ordinary Portland cement; 260 to 320 parts of porous reticular light coarse aggregate; 480 to 560 parts of fine aggregate of 0.15 to 2.5 mm; 6-10 parts of a polycarboxylate superplasticizer; 8-15 parts of modified waste carbon fiber; 60 to 80 parts of fly ash; and 180 to 220 parts of water. According to the porous net-shaped aggregate/carbon fiber composite modified high-temperature-resistant high-strength concrete, a porous net-shaped structure is adopted as light coarse aggregate, the modified carbon fibers are used for reinforcement, and meanwhile the mechanical property and the heat resistance are improved.
本发明提供了一种多孔网状骨料/碳纤维复合改性耐高温高强混凝土，包括以下成分：普通硅酸盐水泥300‑400份；多孔网状轻粗骨料260‑320份；0.15‑2.5mm细骨料480‑560份；聚羧酸系高效减水剂6‑10份；改性废弃碳纤维8‑15份；粉煤灰60‑80份；水180‑220份。本发明的目的是提供一种多孔网状骨料/碳纤维复合改性耐高温高强混凝土，采用多孔网状结构作为轻粗骨料，并用改性碳纤维增强，同时提高力学性能和耐热性能。
