Batching is an initial stage in the concrete manufacturing process, whereas aggregates (such as sand, gravel, or crushed stone), cement, and water should be measured with an accuracy of ±3 percent of the batch quantity and the admixtures with 5 percent of the batch quantity

According to the specification, mixing, moving, placing, and compacting the concrete shouldn't take longer than the cement's initial setting time (30 minutes when using OPC). It must also ensure that segregation takes place
Concrete placement is a crucial step in the building process that calls for meticulous attention to detail and expert execution. It entails the exact placement of newly mixed concrete in the designated spot so that it may serve as the foundation for the structural components of a building or infrastructure. The integrity and durability of the finished construction are directly influenced by the effectiveness of the concrete placing.
To eliminate air voids and ensure maximum strength, the freshly placed concrete must undergo compaction. Vibrators are commonly used to achieve this, as they help the concrete settle into all the nooks and crannies within the formwork
The presence of even 5% and 10% voids in hardened concrete left due to incomplete compaction may result in a decrease in compressive strength by about 30% and 60% respectively
For sturdy and long-lasting constructions, concrete must be cured. Following the rules outlined by the Indian Standards (IS) code is essential to guaranteeing the finest outcomes. Simple information regarding curing concrete in accordance with the IS code is provided below
Finishing is defined as the process of levelling and smoothing the top surfaces of freshly placed concrete to achieve the desired appearance
