Methods of Batching Concrete - The Construction Encyclopedia

The process of measuring ingredients or materials to prepare concrete mix is known as batching of concrete. Batching can be done by two methods, volume batching and weight batching. Batching should be done properly to get quality concrete mix. Methods of Batching Concrete 1. Volume Batching In volume batching, materials are measured on the basis of volume. It […]

Concrete Production - an overview | ScienceDirect Topics

Regarding the cycle of concrete production as a construction material—that is, from cradle-to-gate—(Table 15.5) 74% to 81% of the total CO 2 emission is attributed to the manufacturing of cement (Flower and Sanjayan, 2007). The second major impact is the GGBFS, and third one is coarse aggregate.

Know About the Working of a Concrete Batching Plant

A concrete plant is an equipment that consolidates different elements to make concrete. It is also called a concrete batch mix plant or concrete batching plant. Some of these elements incorporate sand, water, aggregates, fly fiery debris, potash, and concrete. There are two sorts of concrete batching plants: Ready mix plants:

Properties of Concrete - Workability, Setting, Bleeding

Fresh concrete is that stage of concrete in which concrete can be moulded and it is in plastic state. This is also called "Green Concrete". Another term used to describe the state of fresh concrete is consistence, which is the ease with which concrete will flow. The transition process of changing of concrete from plastic state to hardened state.
