Question 1Multiple Correct Options
What are the factors affecting workability of concrete
Question 2
Which following is not the method of volumetric proportioning of concrete?
Question 3
Statement (I): Concrete of desired strength can be achieved by weight-batching method.
Statement (II): Volume-batching method does not take into account bulking of aggregates, hence concrete of desired strength cannot be achieved by volume-batching.
