Basalt fiber concrete
The invention discloses basalt fiber concrete, and each cubic meter of the concrete is prepared from the following raw materials: 360 to 400 kg of cement, 850 to 900 kg of fine aggregate, 950 to 1000 kg of coarse aggregate, 40 to 60 kg of fly ash, 15 to 20 kg of silicon powder, 4 to 6 kg of a water reducing agent, 2 to 4 kg of basalt fiber and 130 to 150 kg of water. The basalt fibers are added into the concrete, so that the generation of micro-cracks can be controlled, and the crack resistance of a prefabricated slab and a joint section of a superposed beam concrete bridge floor can be improved. The basalt fibers are added into the concrete, so that a spatial net-shaped structure can be generated in the concrete, reliable bridging is formed in the concrete, and the overall ductility and strength are improved.
本发明公开了一种玄武岩纤维混凝土，每立方米的混凝土用下列原料制成，水泥360～400kg、细集料850～900kg、粗集料950～1000kg、粉煤灰40～60kg、硅粉15～20kg、减水剂4～6kg、玄武岩纤维2～4kg、水130～150kg。混凝土中玄武岩纤维的加入能控制其微裂缝的产生，可以提高叠合梁混凝土桥面预制板及接缝段抗裂能力。在混凝土中间加入玄武岩纤维，可以使混凝土内部产生空间网状结构，使内部形成可靠“桥接”，从而增加整体延性和强度。
