The invention discloses impact-resistant compressed carbon fiber polymer latex powder composite modified concrete. The impact-resistant compressed carbon fiber polymer latex powder composite modifiedconcrete comprises the following components in percentage by weight: 86.75%-88.85% of a concrete matrix material, 0.15%-0.25% of carbon fibers in a modified admixture and 11%-13% of polymer latex powder, the additives comprise 4.65 kg/m < 3 > of a water reducing agent, 1.16 kg/m < 3 > of a defoaming agent, 2.34 kg/m < 3 > of a coalescing agent and 1.56 kg/m < 3 > of a dispersing agent; wherein cement is Portland cement or ordinary Portland cement with the mark number of 42.5, and sand is medium river sand with the fineness modulus of 2.6-3.0; graded broken stone with the maximum particle sizenot larger than 20 mm is adopted as the stone; FDN efficient water reducing agent mother liquor is adopted as the water reducing agent; and the defoaming agent is a metallic soap common defoaming agent. According to the invention, the multiphase and multi-level characteristics of the concrete material are utilized; through optimized addition of the two admixtures of the carbon fiber and the latexpowder, the carbon fiber and the latex powder are well matched and bonded with the concrete, so that the concrete has high strength, high modulus and high toughness on the whole, the concrete is prevented from being broken, and the impact resistance and the fireproof and anti-knock properties of the concrete are obviously improved.
