Airport drainage ditch slope concrete as well as preparation method and construction method thereof
The invention relates to airport drainage ditch slope concrete in the technical field of concrete preparation. The airport drainage ditch slope concrete comprises the following components in parts by weight: 95-105 parts of cement, 30-35 parts of fly ash, 25-30 parts of slag, 450-458 parts of machine-made sand, 485-495 parts of gravel, 1-2 parts of an air entraining and water reducing agent, 7-9 parts of an accelerator, 35-40 parts of a hydrophobic aid and 65-70 parts of water. The hydrophobic auxiliary agent comprises hydrophobic mineral powder and hydrophobic modified plant fiber in a mass ratio of 1: (0.6-0.8); the treatment method of the hydrophobic modified plant fiber comprises the following steps: firstly, carrying out hydrophobic treatment on plant fiber to obtain hydrophobic plant fiber with a hydrophobic contact angle of 90-150 degrees; and carrying out surface roughness modification treatment on the hydrophobic plant fiber to obtain the hydrophobic modified plant fiber. The method has the effect of improving the form quality and the safety performance of the airport trapezoidal open trench body.
本申请涉及混凝土制备技术领域的一种机场排水沟坡面混凝土，其包括如下重量份的组分：水泥95‑105份、粉煤灰30‑35份、矿渣25‑30份、机制砂450‑458份、碎石485‑495份、引气减水剂1‑2份、速凝剂7‑9份、疏水助剂35‑40份、水65‑70份；疏水助剂包括质量比为1：（0.6‑0.8）的疏水矿物粉和疏水改性植物纤维；疏水改性植物纤维的处理方法：先对植物纤维进行疏水处理，得到疏水植物纤维，疏水植物纤维的疏水接触角度在90‑150°之间；再对所述疏水植物纤维进行表面粗糙度改性处理，得到疏水改性植物纤维。本申请具有提升机场梯形明沟沟体的形态质量和安全性能的效果。
