  • (PDF) Crushed Sand a Substitute for River Sand as a Fine

    — Concrete is a dominant part of construction industry. In India, ordinary concrete contains natural sand obtained from riverbeds as fine aggregates. In recent times with a boost in construction activities, there is a significant increase in the

  • Crushed Glass as an Alternative Fine Aggregate in Concrete

    This study aimed to explore the possibility of utilizing crushed glass as an alternative fine aggregate for concrete by replacing concrete with crushed glass. Specifically, the study sought to assess whether there is a significant correlation between crushed glass volume in concrete and its compressive strength and also between sand volume in

  • M Sand-Manufactured Sand: Eco-Friendly & Economical

    Crushed stone sand can be used as fine aggregates in screed and concrete mixes, in accordance with the standard guidelines, i.e. as per Indian standard IS 383:1970, European standard EN 13139. Crushed sand can be used as a partial replacement or as a blended mixture with natural sand

  • Aggregate Base Course vs. Crushed Concrete Aggregate Base

    Aggregate bases are materials such as sand, gravel or crushed stone that are used to make concrete. Aggregate “base course” refers specifically to the underlying concrete layer of a road or track, over which the wearing course is poured. While aggregate base course is typically made from materials mined directly from the earth, aggregates

  • Concrete Debris as Alternative Fine Aggregate for

    Feb 05, 2012· This experimental study aimed to design a mixture of crushed concrete debris as alternative fine aggregate for architectural finishing mortar. A conventional mortar was compared to concrete debris of the same proportions. Observations from the tests performed were conducted in the laboratory where precise data were gathered and completely attained.
