Premixed colored pervious concrete
Disclosed premixed colored pervious concrete is prepared from the following components in parts by weight: 289 to 306 parts of cement, 51 to 54 parts of fly ash, 15 to 25 parts of a reinforcing agent, 1450 to 1550 parts of coarse aggregate, 3.4 to 3.6 parts of a water reducing agent, 90 to 120 parts of mixing water, 0.51 to 0.54 part of a tackifier and 10 to 15 parts of a coloring agent. The cement is adopted as a main cementing material, the coal ash improves the workability and durability, the reinforcing agent improves the strength of the premixed colored pervious concrete and inhibits surface efflorescence, the tackifier improves the bonding force between slurry and an aggregate interface, and the inorganic coloring agent ensures that the color of a surface layer of the premixed colored pervious concrete is durable and does not fade. In the premixed colored pervious concrete, the slurry can uniformly wrap the aggregate and is clustered by hand holding, the cementing force of the slurry and the aggregate is strong, stones do not fall off for a long time, the permeable rate after hardening is high, the strength is not lower than C20, the color is lasting and does not fade, saltpetering is avoided, and the durability is good.
本发明公开了一种预拌彩色透水混凝土，包括以下重量份的组分：289～306份水泥、51～54份粉煤灰、15～25份增强剂、1450～1550份粗骨料、3.4～3.6份减水剂、90～120份拌合水、0.51～0.54份增黏剂、10～15份染色剂。本发明采用水泥为主要胶结材料，粉煤灰改善和易性及耐久性，增强剂提高预拌彩色透水混凝土的强度，抑制表面泛碱，增黏剂提升浆料与骨料界面胶结力，无机染色剂保证了预拌彩色透水混凝土面层颜色持久不褪色，预拌彩色透水混凝土中浆料能够均匀包裹骨料，手握成团，浆料与骨料胶结力强，石子长久不脱落，硬化后透水率高，且强度不低于C20，颜色持久不褪色，不泛碱，耐久性好。
