Cement Quality The Portland cement is produced base on the specifications outlined in the Malaysian Standard MS 522, which is loosely based on the British standard BS 12. This is however now superseded by EN 196 , which is the European Union standard. The most common requirements that have to comply are:

    a) fineness - blaine method
    b) chemical composition
    c) strength - mortar / concrete cubes
    d) setting time - vicat method
    e) soundness - Le'Chatelier method
