  • Advantages and Disadvantages of Ready-Mix Concrete

    Jul 12, 2021 · (Green concrete is approx. 2.5 tonne per m³.) This problem can be overcome by utilizing so-called 'mini mix' companies which use smaller 4m³ capacity mixers able to reach more-restricted sites. Concrete's limited time span between mixing and curing means that ready-mix should be placed within 210 minutes of batching at the plant.

  • Batching, Mixing, Transporting, and Handling Concrete

    BATCHING Batching is the process of measuring concrete mix ingre-dients by either mass or volume and introducing them into the mixer. To produce concrete of uniform quality, the ingredients must be measured accurately for each batch. Most specifications require that batching be done by mass rather than by volume (ASTM C 94 or AASHTO M 157).
