Composite modified rubber roller compacted concrete and preparation method thereof
The invention discloses composite modified rubber roller compacted concrete and a preparation method thereof, and aims to solve the technical problems that the existing rubber roller compacted concrete material is insufficient in strength, crack resistance and durability. The concrete is mainly prepared from the following raw materials in parts by weight: 45 to 55 parts of coarse aggregate, 35 to 45 parts of fine aggregate, 8 to 12 parts of cement, 5 to 15 parts of rubber particles, 0.02 to 0.04 part of bamboo fiber, 0.03 to 0.05 part of polyvinyl alcohol fiber, 0.12 to 0.16 part of composite modified material, 0.5 to 1.5 parts of high-efficiency water reducing agent and 100 to 140 parts of water. The composite modified rubber roller compacted concrete belongs to a non-toxic and non-corrosive composite material, is excellent in pavement performance, has excellent compressive strength, crack resistance and durability, is wide in raw material sources and low in cost, is environment-friendly and energy-saving in production process, and has high economic and social benefits.
本发明公开了一种复合改性橡胶碾压混凝土及其制备方法，旨在解决现有橡胶碾压混凝土材料强度、抗裂性能和耐久性不足的技术问题。该混凝土的主要制备原料包括：粗骨料45～55份、细骨料35～45份、水泥8～12份、橡胶颗粒5～15份、竹纤维0.02～0.04份、聚乙烯醇纤维0.03～0.05份、复合改性材料0.12～0.16份、高效减水剂0.5～1.5份、水100～140份。本发明复合改性橡胶碾压混凝土属于无毒无腐蚀类复合材料，其路用性能优良、具有优异的抗压强度、抗裂性能和耐久性，且其制备原材料来源广泛、成本低，生产过程环保节能，具有良好的经济、社会效益。
