High-flow-state pervious concrete composition and high-flow-state pervious concrete
The invention relates to the technical field of pervious concrete, and particularly discloses a high-flow-state pervious concrete composition and high-flow-state pervious concrete. The high-flow-state pervious concrete composition is prepared from the following components in parts by weight: 390 to 410 parts of cement, 45 to 55 parts of mineral powder, 45 to 55 parts of fly ash, 110 to 130 parts of machine-made sand, 290 to 310 parts of stone with the particle size of 2.5 to 5.0 mm, 640 to 660 parts of stone with the particle size of 5.0 to 10.0 mm, 490 to 510 parts of stone with the particle size of 10.0 to 15.0 mm, 105 to 115 parts of water, 5 to 7 parts of a water reducing agent and 8 to 12 parts of a pervious concrete reinforcing agent. The high-flow-state pervious concrete is prepared from the high-flow-state pervious concrete composition. The water permeability of the pervious concrete is improved on the basis of ensuring the mechanical property.
本申请涉及透水混凝土技术领域，具体公开了一种高流态透水混凝土组合物和一种高流态透水混凝土。高流态透水混凝土组合物包括以重量份数计的水泥390～410份、矿粉45～55份、粉煤灰45～55份、机制砂110～130份、粒径为2.5～5.0mm的石290～310份、粒径为5.0～10.0mm的石640～660份、粒径为10.0～15.0mm的石490～510份、水105～115份、减水剂5～7份、透水混凝土增强剂8～12份。一种高流态透水混凝土是由所述高流态透水混凝土组合物制备得到。本申请在保证力学性能的基础上提升了透水混凝土的透水性。
