The invention discloses high-strength concrete. The high-strength concrete is prepared from, by weight, 10-12 parts of cement, 35-45 parts of sand, 60-75 parts of coarse aggregate, 13-17 parts of silicon powder, 7-12 parts of rubber powder, 3-5 parts of modified bamboo fibers, 1-4 parts of polyvinyl alcohol fibers and 3-7 parts of polypropylene fibers. By addition of a certain quantity of silicon powder into cement and sand, pressure resistance of the concrete is greatly improved; due to addition of the modified bamboo fibers, the polyvinyl alcohol fibers and the polypropylene fibers, cracking resistance of the concrete is improved while concrete strength is improved as well, and concrete density is reduced to some extent.
