Improved bare concrete and preparation method thereof
The invention belongs to the technical field of concrete processing and manufacturing, and particularly relates to improved fair-faced concrete and a preparation method thereof. Through advantage complementation of rigid fibers and flexible fibers, the toughness of the concrete is effectively improved, the construction difficulty is reduced, and the product quality is improved; the raw materials comprise, by weight, 150-180 parts of ordinary Portland cement, 50-75 parts of mineral powder, 60-80 parts of fly ash, 100-150 parts of quartzite, 120-130 parts of wollastonite powder, 50-70 parts of a water reducing agent, 150-180 parts of polypropylene fibers, 100-130 parts of steel fibers, 200-300 parts of clear water and 55-70 parts of a mortar reinforcing agent, the product has the advantages of being high in bonding strength, high in shrinkage resistance, high in bonding force, stable in performance, capable of reducing environmental pollution and the like, the construction quality can be improved, and the construction cost can be reduced. Materials are saved, the requirement for new development of building environmental protection is met, environmental pollution is reduced, and good economic benefits and social benefits are generated.
