What is the process called in which cement, water, aggregates, and additives are proportioned before mixing concrete?

The process of proportioning cement, water, aggregates, and additives before mixing concrete is known as batching. Batching is a critical step in concrete production because it ensures that the materials are measured accurately to achieve the desired properties of the concrete. The ratios of the components can significantly affect the strength, workability, and durability of the final product.

In batching, the materials are weighed or volume-measured according to a specified recipe or mix design. This careful control of proportions is essential for maintaining consistent quality and performance in the concrete mixture. It helps to avoid issues such as segregation, uneven curing, or variations in strength across different batches.

The other terms listed refer to different stages in the concrete construction process. Curing involves maintaining adequate moisture and temperature conditions to allow the concrete to gain strength after it has been placed. Mixing is the physical process where the batched materials are combined to create a homogenous concrete mix. Pouring is the act of placing the mixed concrete into forms or molds for it to set and harden. Understanding these distinctions is crucial for anyone involved in civil engineering and construction practices.
