Straw fiber reinforcement air-entrained concrete and preparation method thereof

The invention discloses straw fiber reinforcement air-entrained concrete which comprises a base material, an aluminum powder paste, a straw fiber, an additive and water, wherein the doping amount of the aluminum powder paste accounts for 0.06%-0.09% of the dry weight of the base material; the doping amount of the additive accounts for 0.5%-0.8% of the dry weight of the base material; the doping amount of the straw fiber accounts for 2%-10% of the dry weight of the base material; and the mass ratio of the water and the base material is 0.52-0.60, The invention also discloses a preparation method of the straw fiber reinforcement air-entrained concrete. The straw fiber reinforcement air-entrained concrete disclosed by the invention reduces the shrinkage cracking and production cost of air-entrained concrete and solves the problems of straw resource waste, ceramic waste treatment and environmental pollution to a certain degree.
