Hybrid fiber reinforced self-compacting high-strength concrete and preparation method thereof

The hybrid fiber reinforced self-compacting high-strength concrete is prepared from the following components in parts by weight: 405 to 420 parts of cement, 155 to 170 parts of fly ash, 806 to 815 parts of sand, 872 to 890 parts of stone, 8 to 10 parts of water reducing agent, 152 to 160 parts of water, 20 to 40 parts of copper-plated steel fiber, 0.5 to 1.0 part of modified calcium carbonate whisker and 2 to 3 parts of basalt fiber. According to the invention, various and multi-scale hybrid fiber systems are adopted, meanwhile, the calcium carbonate whiskers are subjected to surface modification, and when the calcium carbonate whiskers are applied to preparation of the self-compacting concrete, good mechanical properties, mechanical properties and self-compacting performance can be effectively considered; and the related preparation method is relatively simple and is suitable for popularization and application. 本发明公开了一种混杂纤维增强自密实高强混凝土，各组分及其用量包括：水泥405～420份，粉煤灰155～170份，砂806～815份，石872～890份，减水剂8～10份，水152～160份，镀铜钢
