High-workability tunnel concrete and preparation method thereof
The invention discloses high-workability concrete for a tunnel, and belongs to the technical field of concrete production. The high-workability concrete for the tunnel comprises the following components in parts by weight: 350-500 parts of cement, 900-1100 parts of broken stone, 800-1000 parts of river sand, 15-20 parts of an accelerator, 7-10 parts of an air entraining agent and 150-200 parts of water, the accelerator comprises alum sludge, sodium aluminate, sodium carbonate and quick lime, and the air entraining agent comprises fatty alcohol-polyoxyethylene ether, triterpenoid saponin and sodium alkyl benzene sulfonate. According to the high-workability concrete for the tunnel, through a proper proportion and addition of a proper additive, the flowability of a mixture is remarkably improved, the cohesiveness and the water-retaining property of the mixture are effectively improved, and the high-workability concrete for the tunnel can be widely applied to tunnel construction.
本发明公开了一种高和易性隧道用混凝土，属于混凝土生产技术领域。所述高和易性隧道用混凝土包括以下重量份的组分：350～500份水泥、900～1100份碎石、800～1000份河砂、15‑20速凝剂、7‑10份引气剂和150～200份水，其中，所述速凝剂包括矾泥、铝酸钠、碳酸钠和生石灰，所述引气剂包括脂肪醇聚氧乙烯醚、三萜皂甙和烷基苯磺酸钠。本发明的高和易性隧道用混凝土通过合适的配比，并通过添加合适的外加剂，不仅显着地增加了混合料的流动性，而且有效地提高了混合料的粘聚性和保水性，使得其能够在隧道建设中得到广泛应用。
