Question

How are concrete mixers specified ?

• A. By the number of cement bags used in a batch.
• B. By the nominal volume of concrete that can be mixed in a batch.
• C. By the volume of water used.
• D. By the volume of aggregate used.

Answer 1

The correct option is B By the nominal volume of concrete that can be mixed in a batch.

Concrete mixers specified by volume of mixer and drum revolution speed.
For exmaple : $\left(200T\right)$ , Here the number $"200"$ denotes the volume of the mixer in term of litres and the letter $"T"$ denotes the method of mixing.
