RELATION BETWEEN MIXING TIME AND CONCRETE MIXER TYPE

A study was made of the homogenization and mixing time, and of the relation between standard deviation and mixing time. Concrete mix-design was one of the factors considered in the tests in which three types of mixers were used. Details are given of the measuring techniques utilized, preparation of samples, mix-design, strength, and mixing time.

What is Workability of Concrete? Types, Mechanism - Civil ...

Types, Mechanism. Workability is a property of raw or fresh concrete mixture. In simple words, workability means the ease of placement and workable concrete means the concrete which can be placed and can be compacted easily without any segregation. Workability is a vital property of concrete and related with compaction as well as strength.

Drying Shrinkage

The shrinkage potential of a particular concrete is influenced by the amount of mixing, the elapsed time after the addition of water, temperature fluctuation, slumping, placement, and curing. The makeup of concrete is also very important. Each aggregate and cement type has distinctive characteristics, each contributing to concrete shrinkage.
