  • Finite a more sustainable alternative to concrete made

    Mar 26, 2018 · Sand is worldwide in high demand and heavily used in many industries, especially construction. With deserts full of it, one can easily be fooled into thinking that sand is an almost infinite resource. However, desert sand has little use; the grains are too smooth and fine to bind together, so it is not suitable for the making of for instance concrete.

  • Can Changes in Fine Aggregate Affect Concrete

    A small number indicates a fine grading, and a large number indicates a coarser material. The fineness modulus of the fine aggregate is required for mix proportioning, since sand gradation has the largest effect on concrete workability. Concrete made with a fine sand (low fineness modulus) has much higher paste requirements for good workability.
