Anti-clogging pervious concrete and preparation method thereof
The invention relates to the field of pervious concrete, in particular to anti-blocking pervious concrete and a preparation method thereof. The anti-clogging pervious concrete comprises the following substances in parts by weight: 120-150 parts of coarse aggregate; 400 to 500 parts of cement; 30 to 60 parts of fly ash; 100 to 150 parts of water; 6-8 parts of a functional auxiliary agent; 10 to 15 parts of modified particles; the modified particles are rubber powder particles with the apparent density of 550-600g/L. By adopting the technical scheme, the components of the anti-clogging pervious concrete material are optimized, the phenomenon of abrasion caused by strength reduction in long-term use of the concrete is reduced, the long-acting water permeability of the pervious concrete is improved, and meanwhile, the effective filling of the rubber powder particles is adopted, so that the anti-clogging pervious concrete material has a good anti-clogging effect. Pores formed among the aggregates are deformed to a certain extent under the action of external force, so that the long-acting water permeability of the pervious concrete is improved.
本申请涉及透水混凝土领域，尤其是涉及一种抗堵塞透水混凝土及其制备方法。一种抗堵塞透水混凝土，包括以下重量份物质：粗骨料120～150份；水泥400～500份；粉煤灰30～60份；水100～150份；功能助剂6～8份；改性颗粒10～15份；所述改性颗粒为表观密度550～600g/L的胶粉颗粒。通过采用上述技术方案，本申请通过优化了抗堵塞透水混凝土材料的组分，降低了混凝土长期使用由于强度降低导致出现磨损的现象，改善透水混凝土的长效透水性能，同时本申请采用的胶粉颗粒的有效填充，骨料和骨料之间形成的孔隙在受外力作用下形成一定的形变，改善透水混凝土的长效透水性能。
