Question

Which test used for low workable concretes?

(a) Slump test

(b) Compacting factor test

(c) Flow table test

(d) VeBe test

I had been asked this question by my college director while I was bunking the class.

My question is based upon Measurement of Workability topic in chapter Fresh Concrete of Concrete Technology

Answer 1

Correct choice is (b) Compacting factor test

The best I can explain: The degree of compaction, called compacting factor, is measured by the density ratio, i.e. the ratio of the density of actually achieved in the test to the density of the same concrete fully compacted.
