Abstract
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.
Description
technical field [0001] The present invention relates to a kind of concrete, especially a kind of basalt fiber concrete. Background technique [0002] In bridge engineering, composite beams generally adopt the construction method of prefabricated slabs and cast-in-place joints. The differences in shrinkage, creep, completion and temperature changes between prefabricated slabs and cast-in-place concrete can easily lead to cracking. During the operation period, due to the operation of heavy loads, structural cracks are likely to occur, and cracks at the bottom of the bridge deck are prone to occur, which affects the overall performance of the precast slabs and joints of the composite beam deck. [0003] The concrete acting on it must have lower shrinkage, better bonding ability, and higher ductility. However, the existing ordinary concrete is easy to self-shrink in the early stage, and there will be many micro-cracks in the middle of itself, and ordinary plain concrete is a br...
