Job Mix Concrete Volume
A trial batch of concrete can be tested to determine how much concrete is to be delivered by the job mix. To determine the volume obtained for the job, add the absolute volume V a of the four components—cements, gravel, sand, and water.. Find the V a for each component from. V a = W L / ( SG ) W u . where V a = absolute volume, ft 3 (m 3 )

Concreting in Cold Weather
Definition of Cold Weather Concreting. As per IS Code 7841-2, Any concreting operation done at about 5°C atmospheric temperature or below is termed as cold weather concreting. Effect of cold weather on concrete. Concrete gains its strength due to the hydration of cement. The hydration of cement is a temperature-dependent phenomenon.

What is the problem of over vibration of fresh concrete?
For proper compaction of concrete by immersion vibrators, the vibrating part of the vibrators should be completely inserted into the concrete. The action of compaction is enhanced by providing a sufficient head of concrete above the vibrating part of the vibrators. This serves to push down and subject the fresh concrete to confinement within the...
