How to determination of Consistency of Cement as per IS Code? Is there any reference for taking 400gm of cement for the consistency test?

Hi Kamesh Varan, For a step-by-step process of the mix, design refer IS 10262:2009. Also refer ACI 211.1, for details of mix design and the calculation of quantity. You may also refer IS 456: 2000 for curing and other properties of it also gives the idea of durability and strength of structures.

As Per IS Code 4031:The standard Consistency of a cement is defined as

” A consistency which allow the Vicat Plunger to penetrate to a point 5 mm to 7 mm from the bottom of the mould”.Procedure To Determine The Consistency Of the Cement:1- Prepare the cement paste weighed 300 grams with potable water of known quantity.

2-Taking utmost care that preparation time is between 3 mins to 5 mints and do not exceed the time.

3-Fill the vicat mould with cement paste.

4-Smooth the top layer of the cement paste.

5-Trowel should be use for all the above process to determine the normal consistency of cement.

6- Place the sample under the rod bearing the plunger.

7- Lower the plunger slowly to touch the surface of the test block and quickly release it, allowing it to penetrate in the paste.

8- Write the record depth of the penetration.

9- Try it on others samples with different amount of water, test it as the above procedure.

FOEMULA’S USED ;Standard Consistency (%) = Weight of water added /Weight of cement *100

Answer to 2nd Question:There is no refrence of taking 400gms of cement for consistency test,as per IS CODE 4031.
