Sleeper concrete
The invention discloses sleeper concrete. The sleeper concrete is prepared from the following raw material components: cement, rubber aggregate, machine-made sand, gravel, fly ash ceramsite, a water reducing agent and water. The rubber aggregate is added into the concrete, so that the elasticity of the sleeper concrete can be effectively enhanced, the impact resistance of the sleeper concrete is improved, and the risk of sleeper cracking is reduced; by adding the rubber aggregate, the thermal expansion coefficient of the concrete can be reduced to a certain extent, so that the influence of temperature on the concrete is reduced, and the performance is more suitable for the application environment where the sleeper is located; and meanwhile, by adding the lightweight and porous fly ash ceramsite, the elasticity modulus of the concrete is further reduced, the impact resistance of the concrete is improved, and the fly ash ceramsite can form a porous honeycomb structure in a concrete system, so that the influence of temperature change on the concrete can be reduced to a certain extent, and the frost resistance of the concrete is enhanced.
本发明公开一种轨枕混凝土，所述轨枕混凝土包括以下原料组分：水泥、橡胶集料、机制砂、碎石、粉煤灰陶粒、减水剂以及水。本发明在混凝土中添加橡胶集料，能够有效增强轨枕混凝土的弹性，提高其抗冲击性能，从而降低轨枕开裂的风险，且通过添加橡胶集料，还能在一定程度上降低混凝土的热膨胀系数，从而降低温度对其的影响，使其性能更适用于轨枕所在的应用环境；同时，通过添加轻量且多孔的粉煤灰陶粒，进一步降低了混凝土的弹性模量，提升了其抗冲击性能，且粉煤灰陶粒能够在混凝土体系中形成多孔蜂窝结构，在一定程度上能够降低温度变化对混凝土的影响，增强其抗冻性能。
