High-water-permeability concrete and preparation method thereof
The invention provides high-water-permeability concrete and a preparation method thereof. The high-water-permeability concrete is prepared from the following raw materials in parts by weight: 500-800 parts of cement, 15-33 parts of fly ash, 22-38 parts of construction waste fine aggregate, 11-25 parts of nano silicon powder, 5-9 parts of a water reducing agent, 16-50 parts of an organic expanding agent, 9-12 parts of a seepage agent and 80-100 parts of water. According to the invention, the raw materials are matched with each other to synergistically play a role in high water permeability, the characteristics of a concrete matrix are changed, the porosity is increased, the infiltration capacity is improved by adjusting the cement consumption and the water-cement ratio and using admixture materials such as fly ash, adjuvants such as an organic expanding agent and a seepage agent are added, and the construction waste fine aggregate is modified, so that the construction waste fine aggregate is modified. The flowability and pore structure of the concrete are effectively adjusted, and the compressive strength of the concrete can be improved while proper water permeability is achieved.
本发明提供一种高透水性混凝土及其制备方法，包括以下重量份原料：水泥500‑800份、粉煤灰15‑33份、建筑垃圾细骨料22‑38份、纳米硅粉11‑25份、减水剂5‑9份、有机膨胀剂16‑50份、渗流剂9‑12份、水80‑100份；本发明通过各原料之间的相互配比，协同发挥其高透水性的作用，通过调整水泥用量、水灰比和使用粉煤灰等掺合材料，改变混凝土基质的特性，增加孔隙率，提高渗透能力，加入有机膨胀剂、渗流剂等辅助剂，以及对建筑垃圾细骨料进行改性，有效调节混凝土的流动性和孔隙结构，在达到适当的透水性的同时，还能提高混凝土的抗压强度。
