Lightweight ecological ultra-high performance concrete sound barrier unit plate capable of absorbing automobile exhaust and preparation method of lightweight ecological ultra-high performance concrete sound barrier unit plate
The invention discloses a light ecological ultra-high performance concrete sound barrier unit plate capable of absorbing automobile exhaust and a preparation method of the light ecological ultra-high performance concrete sound barrier unit plate, and belongs to the technical field of concrete sound barrier materials. The sound barrier unit plate comprises a unit plate formed by pouring ultra-high performance concrete and a spraying layer, wherein the ultra-high performance concrete is prepared from the following raw materials in parts by weight: 540 to 615 parts of cement, 185 to 255 parts of fly ash, 170 to 240 parts of silica fume, 145 to 175 parts of limestone powder, 610 to 695 parts of fine aggregate, 22.9 to 29.3 parts of water reducing agent, 0.63 to 0.83 part of defoaming agent, 0.031 to 0.048 part of air entraining agent, 36 to 60 parts of nano titanium dioxide, 160 to 200 parts of steel fiber and 177 to 189 parts of water; the fine aggregate is spherical pottery sand, and the bulk density is not greater than 900 kg/m < 3 >; the spraying layer is prepared from the following raw materials in parts by weight: 4 to 6 parts of a composite nano photocatalyst, 0.25 to 0.50 part of a dispersing agent, 0.75 to 1.25 parts of a light stabilizer and 12 to 15 parts of water. The concrete sound barrier unit plate disclosed by the invention can effectively insulate sound, reduce noise and purify automobile exhaust, and still has excellent working performance, mechanical property and durability on the premise that the cement content is lower than 55%.
本发明公开了一种可吸收汽车尾气的轻质生态超高性能混凝土声屏障单元板及其制备方法，属于混凝土声屏障材料技术领域。所述声屏障单元板包括由超高性能混凝土浇筑而成的单元板和喷涂层，所述超高性能混凝土的原料包括：水泥540～615份、粉煤灰185～255份、硅灰170～240份、石灰石粉145～175份、细骨料610～695份、减水剂22.9～29.3份、消泡剂0.63～0.83份、引气剂0.031～0.048份、纳米二氧化钛36～60份、钢纤维160～200份、水177～189份；所述细骨料为球型陶砂，堆积密度不大于900kg/m3；所述喷涂层的原料包括：复合纳米光催化剂4～6份、分散剂0.25～0.50份、光稳定剂0.75～1.25份、水12～15份。本发明的混凝土声屏障单元板可有效隔音消音以及净化汽车尾气，在水泥含量低于55％的前提下仍具有优异的工作性能、力学性能和耐久性能。
