Green approach on ternary blended pre stressed cement concrete railway sleepers

Conventional Railway concrete sleepers are manufactured using steel pre-stressed strands upto pre-determined stress level surrounded by well compacted controlled concrete. The concrete used in manufacturing of railway sleepers is made up of 53 grade ordinary Portland cement with natural aggregates. Though, experiments have been conducted worldwide with various unorthodoxical constituent materials, the standardization of such non-conventional materials used for concrete sleeper manufacturing on Indian Railways (IR) is yet to be established. The pretensioned prestressed concrete (PSC) sleepers for Broad Gauge (BG) should pass the specified acceptance criteria T 39-85 of 2011 as per the Indian Railway Standard specification issued by Research Design Standard Organisation (RDSO).
