Expressway concrete ditch cover plate as well as preparation method and application thereof
The invention belongs to the technical field of engineering materials, and particularly relates to an expressway concrete ditch cover plate and a preparation method and application thereof.The expressway concrete ditch cover plate is prepared from, by weight, 115-135 parts of cement, 12-16 parts of silica fume, 280-290 parts of medium sand, 420-430 parts of granite, 0.8-1 part of basalt fiber of 3 mm, 1.5-2 parts of basalt fiber of 19 mm, 15-20 parts of polycarboxylate superplasticizer and 65-70 parts of water; the preparation method comprises the following steps: uniformly mixing the raw materials, and then sequentially carrying out the steps of pouring, vibrating, curing and demolding. The highway trench cover plate prepared by the invention has excellent mechanical properties and ultimate load, and can reduce the thickness, weight and labor intensity of the cover plate on the premise of meeting the standard and design requirements; meanwhile, waste is turned into wealth, a large amount of fluorgypsum is consumed, energy and resources are saved, and the national sustainable development strategy is met.
本发明属于工程材料技术领域，具体涉及一种高速公路混凝土沟盖板及其制备方法、应用，按重量份计，所述盖板的原料包括：水泥115‑135份，硅灰12‑16份，中砂280‑290份，米石420‑430份，3mm玄武岩纤维0.8‑1份，19mm玄武岩纤维1.5‑2份，聚羧酸减水剂15‑20份，水65‑70份，氟石膏粉末55‑65份和氟硅酸盐15‑20份，制备方法为将所述原料拌合均匀后，依次进行浇注、振捣、养护、脱模步骤；本发明制备的高速公路沟盖板，具有优异的力学性能及极限荷载，在满足标准及设计要求的前提下，能够减小盖板的厚度，减轻重量和劳动强度；同时变废为宝，大量消耗了氟石膏，节约了能源和资源，符合国家可持续发展战略。
