Durable concrete and preparation method thereof
The invention discloses durable concrete and a preparation method thereof, and relates to the technical field of building materials. The high-strength concrete is prepared from the following raw materials in parts by weight: 300 to 400 parts of cement, 400 to 500 parts of fine aggregate, 700 to 800 parts of coarse aggregate, 15 to 25 parts of coal gangue powder, 10 to 15 parts of high bauxite, 8 to 10 parts of phosphorus slag powder, 10 to 20 parts of limestone powder, 8 to 12 parts of super absorbent polymer, 10 to 20 parts of admixture, 20 to 40 parts of nanofiber and 120 to 220 parts of water. The durable concrete disclosed by the invention is high in compressive strength, good in anti-cracking and anti-seepage effects, excellent in durability and long in service life.
