Anti-abrasion ultra-high performance concrete and construction method thereof
The invention relates to the technical field of concrete, and particularly provides abrasion-resistant ultra-high performance concrete and a construction method thereof. Wherein the concrete is prepared from the following components in parts by weight: 100 to 150 parts of modified superfine cement, 180 to 210 parts of wear-resistant aggregate, 40 to 60 parts of water, 15 to 20 parts of fly ash, 30 to 40 parts of S95 slag powder, 15 to 20 parts of alumina fine powder with the particle size of less than or equal to 0.074 mm, 4 to 5 parts of water reducing agent and 1 to 5 parts of reinforced fiber; wherein the modified cement is prepared by the following method: adding S95 slag powder, fly ash, a grinding aid and a rheology modifier into cement, and grinding to prepare modified superfine cement with the specific surface area of 800-1000m < 2 >/kg; the weight ratio of the cement to the S95 slag powder to the fly ash to the grinding aid to the rheology modifier is (52-60): (20-30): (10-15): (2-6): (1-3). According to the abrasion-resistant ultra-high-performance concrete provided by the embodiment of the invention, the abrasion-resistant ultra-high-performance concrete with strong abrasion resistance, high strength and excellent construction performance is formed by virtue of chemical reaction and synergistic effect among the components of the materials.
