The invention relates to the technical field of building materials, in particular to a pervious concrete reinforcing agent which comprises the following components in percentage by mass: 10-25% of water reducing agent, 30-75% of micro powder, 0.5-2.2% of alkali-resistant glass fiber powder, 0.5-2.2% of hydroxypropyl methyl cellulose, 1.5-3.5% of sodium lignin sulfonate, 1.5-10.5% of polyurethane emulsion, 0.5-2.2% of calcium oxide, 0.5-2.2% of sodium nitrite and 1.5-10.5% of water. Silicon powder and a naphthalene water reducer are mixed according to the proportion of 3: 1, and then are mixedwith a water retaining agent, a retarder, a thickening agent and an anti-freezing agent to obtain the reinforcing agent, the reinforcing agent can ensure the water permeability of the pervious concrete, and the performance of the concrete, especially the compression resistance and the bending resistance; and the fluidity and slump of the concrete can be improved, the effect of the reinforcing agent is considered, and the cost control is combined, so that the reinforcing agent has the advantages of higher cost performance, low cost, good effect and the like.
本发明涉及建筑材料技术领域，具体涉及一种透水混凝土增强剂，其按质量百分比的组成成份如下：减水剂10‑25％、微粉30‑75％、耐碱玻璃纤维粉0.5‑2.2％、羟丙基甲基纤维素0.5‑2.2％、木质素磺酸钠1.5‑3.5％、聚氨酯乳液1.5‑10.5％、氧化钙0.5‑2.2％、亚硝酸钠0.5‑2.2％、水1.5‑10.5％；它采用硅粉和萘系减水剂按3:1的比例，再混合保水剂、缓凝剂、增稠剂以及防冻剂形成增强剂，它能够保证透水混凝土的透水性的同时还具有混凝土自身的性能，特别是抗压度和抗折度；且能够改善混凝土的流动性和塌落度，既考虑增强剂的效果又结合成本控制，使得其具有较高的性价比，具有成本低、效果好等优点。
