Why Batching of Concrete is Important? - GharPedia

Concrete mix made by the batching process is very cohesive. Batching of concrete ingredients also rectify the bulkage correction because excessive water can cause loss of cohesiveness and can also lead to segregation or bleeding in concrete which results in poor quality of concrete. If any batching errors in cement and fine aggregates (sand), the mixing of concrete ingredients is not well and this can lead to poor finish and variation of texture.

Concrete Batching - an overview | ScienceDirect Topics

While dust is the principal waste of cement and aggregate production, wastes derived from concrete batching include mixer washout, sludge and returned excess of fresh concrete (Gursel et al., 2014). On average, the amount of waste generated by the ready-mix concrete sector is up to 0.45% of the total production, with a maximum of about 5%–9% in times of great demand ( WBCSD/CSI, 2009 ).

What do you mean by Batching of Concrete?

Poor batching also results into porous concrete which becomes the reason of leakages in the house. The porous concrete may be the reason of corrosion and will ultimately reduce the life of the structure and increase the cost of repairs. Traditionally batching of concrete is done by volume. Batching accuracy is important. It is however preferred to do weigh batching rather than volume batching. Volume batching may be allowed only where weigh batching is not practical.

Apr 23, 2007 · Many cement companies and the Portland Cement Association wrote pamphlets on how to make and place concrete on the farms. Since it was not easy to weigh the cement, sand, and stone, batching was done by volume. To make batching easier, cement was put in 1-cubic-foot bags. This made measuring the volume of cement unnecessary.
