摘要
采用对比试验方法,系统研究了磷矿渣比表面积和掺量对轨枕混凝土力学性能的影响,并分析了磷矿渣的作用机理,结果表明:蒸汽养护条件下,适当粒度和掺量的磷矿渣可以有效改善轨枕混凝土的力学性能,从而为磷矿渣混凝土轨枕的实际应用打下良好基础。
Presents a detailed experimental study about the influence of phosphorus slag on the mechanical property of sleeper concrete by the correlation method and its mechanism is analysised.The results demonstrated that phosphorus slag with appropriate cement replacement dosage and specific area could improve the mechanical property of sleeper concrete under the steam curing and could also be regarded as a good foundation for the practical application of concrete sleeper adding phosphorus slag.
