Inorganic-organic composite powder reinforcing agent for pervious concrete and application of inorganic-organic composite powder reinforcing agent
The invention relates to an inorganic-organic composite powder reinforcing agent for pervious concrete and application of the inorganic-organic composite powder reinforcing agent. The reinforcing agent comprises the following components in parts by weight: 66-71 parts of silica fume, 18-22 parts of redispersible latex powder, 10-11 parts of an early strength agent, 0.7-0.9 part of a water reducing agent and 0.01-0.05 part of a [beta]-cyclodextrin-carbon nanotube compound, and during application, the reinforcing agent is added in the mixing process of pervious concrete, and the mixing amount of the reinforcing agent is 4-6% of the mass of cement. Compared with the prior art, the preparation method has the advantages that inorganic reinforcing and organic toughening composite modification methods are combined, and specific components are mixed according to a certain proportion, so that the cohesion performance and the adhesion performance of cement mortar can be effectively improved, and the compressive strength and the breaking strength of the pervious concrete are improved on the premise of keeping the same porosity; and the freeze-thaw durability is also well improved.
本发明涉及一种透水混凝土用无机‑有机复合粉体增强剂及其应用，增强剂包括以下组分及重量份含量：硅灰66‑71份、可再分散性乳胶粉18‑22份、早强剂10‑11份、减水剂0.7‑0.9份及β‑环糊精‑碳纳米管复合物0.01‑0.05份；应用时，增强剂在透水混凝土的拌合过程中加入，并且增强剂的掺量为水泥质量的4％‑6％。与现有技术相比，本发明结合了无机增强和有机增韧的复合改性方法，通过将特定组分按一定比例进行混合，可有效改善水泥胶浆的内聚性能和黏附性能，进而在保持相同孔隙率的前提下改善透水混凝土的抗压强度和抗折强度，对冻融耐久性也具有良好的改善效果。
