Fair-faced concrete and concrete construction method
The invention discloses fair-faced concrete and a concrete construction method, the fair-faced concrete comprises the following main components: water, cement powder, coarse aggregate, fine aggregate, fly ash and an additive, the coarse aggregate is composed of gravels and pebbles, the fine aggregate is composed of limestone powder, dolomite powder and river sand, and the additive is composed of fly ash and fly ash. The admixture is composed of a water reducing agent, an early strength agent, a waterproof agent and an anti-freezing agent, and the material of the water reducing agent is lignosulfonate. According to the fair-faced concrete, the gravels, the pebbles, the limestone powder, the dolomite powder and the river sand are added into the fair-faced concrete, so that the overall functionality of the fair-faced concrete can be greatly improved, the influence of the external environment on the fair-faced concrete is reduced, the concrete exposed to the outside is prevented from being corroded and damaged, and meanwhile, the functionality of the water reducing agent, the early strength agent, the waterproof agent and the anti-freezing agent is wide; and most of the selected materials are environment-friendly materials, so that the environmental pollution can be effectively reduced, a scientific beneficial substance ratio is formed, and the material is more suitable for being used in a severe environment.
本发明公开了一种清水混凝土及混凝土施工方法，所述清水混凝土的主要成分为：水、水泥粉、粗骨料、细骨料、粉煤灰和外加剂，所述粗骨料由碎石和卵石组成，所述细骨料由石灰岩粉、白云岩粉和河沙组成，所述外加剂由减水剂、早强剂、防水剂和防冻剂组成，所述减水剂的材质为木质素磺酸盐。本发明通过在清水混凝土的内部添加碎石、卵石、石灰岩粉、白云岩粉和河沙，能够大幅提高清水混凝土的整体功能性，减少外部环境对其造成的影响，避免暴露在外部的混凝土出现腐蚀损坏，同时减水剂、早强剂、防水剂和防冻剂的功能性较广，而且所选材料多为环保性材料、能有效减少环境污染，使其形成科学的有益物质配比，更适合恶劣环境使用。
