Pervious concrete additive and pervious concrete
The invention discloses a pervious concrete additive and pervious concrete.The pervious concrete additive is composed of modified glass fibers and lignin-ionic liquid composites.In the pervious concrete additive, the surfaces of the modified glass fibers are coated with carbon nanotubes, so that the strength of concrete is improved, and the permeability of the concrete is improved; meanwhile, through the synergistic effect between the modified glass fibers and the lignin-ionic liquid composite material, the compressive strength and breaking strength of the concrete are improved, and the water permeability of the concrete is also improved; the zeolite and the lignin-ionic liquid composite material have porous structures and can enhance the water permeability effect of the concrete, meanwhile, the lignin-ionic liquid composite material has high hydrophobicity, the formed water-permeable concrete has many fine pores, and hydrophobic lignin fibers near the pores can accelerate water passing and enhance the water permeability effect.
本发明公开了一种透水混凝土添加剂及透水混凝土，透水混凝土添加剂由改性玻璃纤维和木质素‑离子液体复合材料所组成，本发明提供的透水混凝土添加剂中，改性玻璃纤维的表面包覆有碳纳米管，不仅提高了混凝土的强度，而且提高了混凝土的和易性，同时改性玻璃纤维和木质素‑离子液体复合材料之间通过协同作用，既提高了混凝土的抗压强度和抗折强度，同时还提高了混凝土的透水性能；沸石和木质素‑离子液体复合材料均具有多孔的结构，可以增强混凝土的透水效果，同时，木质素‑离子液体复合材料具有较高的疏水性，成型后的透水混凝土存在许多细小孔隙，孔隙附近的疏水木质素纤维能加快水分通过，增强透水效果。
