High-permeability concrete and preparation method thereof
The invention provides high-permeability concrete and a preparation method thereof.The high-permeability concrete is composed of cement, aggregate, a water reducing agent, a permeability modifier and a strength modifier, the permeability modifier is composed of coal ash powder and modified porous bamboo charcoal, and the coal ash powder and the modified porous bamboo charcoal are matched with the strength modifier, so that the binding capacity of the permeability modifier with the cement and the aggregate is enhanced; after concrete curing is completed, the concrete can have a porous internal structure on the premise that high strength is kept, water vapor in a building can be discharged through the porous internal structure, the air permeability of the concrete is greatly improved, and the concrete has the advantages that the service life of the building is prolonged, the living experience is improved, and popularization and implementation are convenient.
本申请提供一种高透气性混凝土及其制备方法，由水泥，骨料，减水剂，透气性改性剂以及强度改性剂组成，其中透气改性剂由煤灰粉以及改性多孔竹炭组成，通过两者与强度改性剂配合，使得透气改性剂与水泥和骨料的结合能力增强，当混凝土养护完成后，混凝土可在保持高强度的前提下，具有多孔内部结构，使得建筑内水汽可由多孔内部结构排出，大大提升了混凝土的透气性能，具有延长建筑使用寿命，提升居住体验，便于推广实施的优点。
