在混凝土中掺加Ⅰ级粉煤灰、磨细水淬矿渣粉及复合型高性能混凝土外加剂,配制轨枕用C60混凝土,可在保证轨枕静载、疲劳等力学性能不降低的前提下,提高混凝土的工作性及长期与耐久性能,同时可明显改善轨枕的抗裂性和疲劳稳定性能,从而大幅度地提高混凝土轨枕的使用寿命。 In the concrete mixed with grade I fly ash, grinding water quenching slag powder and composite high performance concrete admixture, preparation of sleeper C60 concrete, can ensure sleeper static load, fatigue and other mechanical properties under the premise of not reducing Concrete workability and long-term and long-term performance, at the same time can significantly improve the sleeper crack resistance and fatigue stability, thereby greatly improving the service life of concrete sleepers.
