  • Concrete: Batching and Mixing | Concrete Technology

    If each batch represents 140 litre of wet concrete, then output per day. = 140 x 140 = 196000 litres or 19.6 m 3 per day. For mixers having capacity more than 800 litres Orchard has suggested the output as. = K x nominal capacity of mixer. where, K = 0.65 for tilting drum mixers, and. K = 0.72 for non-tilting mixers.

    10/12/2020 · The quality of concrete may differ because of the bulkage of fine aggregate, and therefore concrete may not be uniforms and consistent. Volume batching is performed using gauged boxes of inside dimensions of 350 millimeters by 400 millimeters by 250 millimeters. The box volume is 0.35 cubic meters, equivalent to the volume of one bag of cement.

  • What do you mean by Batching of Concrete? - GharPedia

    Batching is the process in which the quantity or proportion of materials like cement, aggregates, water, etc. are measured on the basis of either weigh or volume to prepare the concrete mix. Proper Batching improves the workability of concrete by reducing the segregation or bleeding in concrete.
