    Dear Sir / Madam

    USE OF GRANITE FINES AS SUBSTITUTE FOR NATURAL SAND IN CONCRETE

    Objective
    This circular aims to remind the industry to adopt the use of granite fines as substitute
    for natural sand in concrete.

    Background
    2 In Dec 2007, BCA issued a circular allowing 100% replacement of natural sand with
    granite fines in concrete, of which the quality and grading shall be in accordance with SS EN
    12620. Granite fines have been successfully used in Singapore for numerous building projects
    of various nature and test results showed that such concrete mix is able to achieve the desired
    workability and strength.

    3 The use of granite fines is a more sustainable way forward. BCA is working with major
    Government Procurement Entities (GPEs) and ready-mixed concrete producers to adopt a
    higher substitution of natural sand with granite fines. The Institution of Engineers, Singapore
    (IES) and Association of Consulting Engineers Singapore (ACES) are also supportive of this
    effort.

    For Clarification
    4 We would appreciate it if you could bring to the attention of your members the content
    of this circular. Should you need any clarification, please submit your enquiry through BCA’s
