High-performance pervious concrete and application thereof
The invention discloses high-performance pervious concrete. The high-performance pervious concrete is prepared from the following components in parts by mass: 400 to 590 parts of saturated surface drycoarse aggregate, 100 parts of a cementing material, 27 to 31 parts of water, 0.6 to 1.1 parts of a water reducing agent and 0.005 to 0.01 part of a thickening agent. By utilizing the coupling effectof the water reducing agent and the thickening agent, the viscosity of the neat paste is increased while the fluidity of the neat paste is improved, so that the uniformity of the paste in the pervious concrete is improved, the working performance of the pervious concrete is maintained, and the contradiction between the mechanical property and the water permeability of the pervious concrete is improved. The matching design of rocks with different strengths and concrete and the structural design under the heavy load condition are carried out, so that ore resources are effectively utilized, thestrength of the pervious concrete is improved, and the contradiction between the mechanical property and the water permeability of the pervious concrete is improved.
本发明公开了一种高性能透水混凝土，按质量份数包括以下组分：饱和面干粗骨料400‑590份，胶凝材料100份，水27‑31份，减水剂0.6‑1.1份，增稠剂0.005‑0.01份。本发明利用减水剂与增稠剂的耦合作用，在提高净浆流动度的同时增加净浆的粘度，从而提高浆体在透水混凝土中的均匀性，保持透水混凝土的工作性能，改善透水混凝土力学性能与透水性能的矛盾。本发明进行了不同强度岩石与混凝土的匹配性设计与重载条件下结构设计，从而有效利用矿石资源，提高透水混凝土的强度，改善透水混凝土力学性能与透水性能的矛盾。
