Batching, Mixing, Transporting, and Handling Concrete, Chapter 10

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).

Methods of Batching Concrete - The Constructor

Methods of Batching Concrete 1. Volume Batching. In volume batching, materials are measured on the basis of volume. It is less precise method of batching; Measurement boxes or gauge boxes of known volume are used to measure materials. Cement is taken in the form of bags, where volume of one bag of cement (50 kg) is taken as 35 liters.

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.

Types Of Batching Of Concrete | Weigh Batching | Volume Batching

Weigh Batching of Concrete: Weigh batching of concrete is accomplished with the use of a weigh batch or the weighing system on the batching plant. On big projects, automatic batching plants are set up to facilitate optimizing quality and uniformity. Water is very vital material and therefore, maximum water should be used for batching.

Batching, Mixing, Placing and Compaction of Concrete

Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...

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 ).

Site Batching of Concrete| Concrete Construction Magazine

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.
