    In this study it was investigated that the effect of the crushed sand on fluidity and compressive strength properties of high performance concrete. Blending crushed sand FM 3.98 produced in Namyangju, Kyunggido and sea sand FM 2.80 produced in Asan bay in Chungnam. The final FMs of fine aggregate were 3.50, 3.23, and 3.08.

  • Aggregates - Portland Cement Association

    Aggregates - Portland Cement Association

    Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed crushed, screened, and washed to obtain proper cleanliness and gradation.

    PROPERTIES OF AGGREGATES FOR CONCRETE -

    The choice of aggregate is determined by the proposed use of the concrete. Normally sand, gravel, and crushed stone are used as aggregates to make concrete. The aggregate should be well-graded to improve packing efficiency and minimize the amount of cement paste needed. Also, this makes the concrete more workable.
