Question 1

Consider following statement regarding tests on cement

1) For a sound cement, expansion due to lime in Le chatelier method shall not be more than 10 cm

2) Autoclave test is used to measure soundness due to presence of magnesia in cement.

3) In vicat’s apparatus to determine setting time of cement, 10 mm diameter plunger is used to determine initial setting time.

4) Blair’s air permeability method is used to determine fineness of cement.

Correct statement(s) is/are:

Question 2

Which one of the following cements is a deliquescent?

Question 3

Direction: In the following question consists of two statements Assertion(A) and Reason(R). You have to read the statements carefully and select the answers to these questions using the options below.

Assertion (A): The amount of cement paste should be sufficient to cover the surface of all particles for proper workability and bond .
Reason(R): the water cement ratio is fixed accordingly.

Question 4

Direction: In the following question consists of two statements Assertion(A) and Reason(R). You have to read the statements carefully and select the answers to these questions using the options below.

Assertion (A): In order to obtain higher degree of workability in cement concrete, both water content and proportion of cement should be increased.
Reason(R): Increase in water cement ratio decreases the strength of cement concrete, a mix with higher workability must have higher proportion of cement in it.

Question 5

Statement-I : Finer grinding of cement results in early development of strength.
Statement-II : Rate of hydration of cement is increased when it is ground finer.

Question 6

Match List-I with List – II and choose the correct option using the codes given below :

Question 7

The discharge through a weir is 1.62 m³/s. Find the discharge through the model of the weir, if the horizontal dimension of prototype is 60 times the horizontal dimension of the model and vertical dimension of prototype is 9 times the vertical dimension of the model:

Question 8

Which of the following statements is NOT correct

Question 9

A model having scale ratio of 1 : 40 is built for a rectangular weir over the river. The average depth of water in the river is 3.5 m. If the force acting on the model was calculated to be 3.0 N, the force acting on the prototype would be:

Question 10

The flow in a river is 1800 cumecs. A distorted model is built with horizontal scale of 1/100 and vertical scale of 1/25.The flow rate in the model should be
