Pre-mixed anti-crack pervious concrete for heavy-load composite pervious pavement and preparation method of pre-mixed anti-crack pervious concrete
The invention discloses premixed anti-crack pervious concrete for a heavy-load composite pervious pavement and a preparation method of the premixed anti-crack pervious concrete, and relates to the technical field of concrete materials, the premixed anti-crack pervious concrete for the heavy-load composite pervious pavement is prepared from the following raw materials in parts by weight: 420-480 parts of cement, 1600-1700 parts of gravel, 10-30 parts of an anti-crack reinforcing agent and 0.5-1.5 parts of a premixed component, the anti-cracking reinforcing agent is prepared from ethylene-vinyl acetate copolymer modified emulsion powder, nano silicon dioxide, graphene oxide and silica fume. The composite reinforcing and toughening technology and the premixing technology are combined, the cohesion performance and the adhesion performance of the pervious concrete mixture are effectively improved, the technological requirements of premixing production, transportation, paving and the like can be met, and then the strength and toughness of the pervious concrete are improved on the premise that the same porosity is kept.
本发明公开了重载复合透水路面用预拌抗裂透水混凝土及其制备方法，涉及混凝土材料技术领域，该重载复合透水路面用预拌抗裂透水混凝土由以下重量份数的原料组成：水泥420‑480份、碎石1600‑1700份、抗裂增强剂10‑30份，预拌组分0.5‑1.5份，纤维2‑10份及水120‑140份，抗裂增强剂包括乙烯‑醋酸乙烯酯共聚物改性乳液粉末、纳米二氧化硅、氧化石墨烯及硅灰。本发明结合了复合增强增韧技术与预拌化技术，有效改善了透水混凝土拌合物的内聚性能和黏附性能，能够满足预拌生产、运输、摊铺等工艺需求，进而在保持相同孔隙率的前提下改善透水混凝土的强度和韧性。
