Novel rubber concrete vibration reduction sleeper
The invention provides a novel rubber concrete vibration reduction sleeper. The novel rubber concrete vibration reduction sleeper is composed of raw materials by weight: 10-50 kg/m<3> of rubber, 280-310 kg/m<3> of cement, 40-60 kg/m<3> of fly ash, 40-70 kg/m<3> of mineral slag, 680-700 kg/m<3> of sand, 1000-1200 kg/m<3> of stones, 150-170 kg/m<3> of water and 2-4 kg/m<3> of a water reducing agent.Specific novel rubber concrete is prepared by adopting processes such as grinding waste rubber tires into powder, adopting a polycarboxylate-type high-efficiency water reducing agent and controllingthe expansion rate of a mortar rod of a coarse aggregate, and meanwhile, a novel functional material which is excellent in damping effect, high in strength, economical and environment-friendly is prepared by matching with a reasonable damping sleeper preparation method, so that the novel rubber concrete has wide popularization and application values.
本发明提供一种新型橡胶混凝土减振轨枕，该种新型橡胶混凝土减振轨枕的原材料组成，按重量计，包括：橡胶10‑50kg/m3、水泥280‑310kg/m3、粉煤灰40‑60kg/m3、矿渣40‑70kg/m3、砂680‑700kg/m3、石子1000‑1200kg/m3、水150‑170kg/m3、减水剂2‑4kg/m3，其中采用废旧橡胶轮胎磨细成粉，采用聚羧酸系高效减水剂，控制粗骨料的砂浆棒膨胀率等工艺来制备特异的新型橡胶混凝土，同时配合合理的减振轨枕制备方法，制备出一种减震效果优异、强度高、经济环保的新型功能材料，具有广泛的推广使用价值。
