this video explains on initial setting time of cement now we are going to see the initial setting time of cement and we are going to see how we will do the experiment so this is wicked apparatus and this is wicked mold so this is plunger which is of 1mm square so this is cement no measuring job which consists of water and weighing balance now we have to take this cement and remove the lumps in the cement the lumps should be removed and now we are tearing the weighing balance now disabled now we are putting the cement in the weighing balance and taking 250 grams of cement so you have to take it 250 grams of cement the cement should be placed in the class board after putting this women from the normal consistency of the cement which we have done in the last video so which we have done before itself so normal constancy of cement we are getting 32 percentage of water in 6mm penetration so 32 percentage of water to be added in the initial setting time of cement so 32 percentage of this percentage of water is added into 0.85 times of water is reduced so we are going to add No 68 ml of water in this event to find out the initial setting time so now we are pouring 50 ml of water in the measuring jar the 50 ml of water so now we are pouring the water in this event which is a 50 ml to replace now this filament is mixed properly so from so this amount is being well mixed and we should see that there is no lumps particle present in the mix now we are going to take the wicket of our test we could set up and the plunger has been placed at the bottom of the wicked apparatus and this will hold it on the top now the Wicked mold is removed so timing is very important in this experiment so first as the water is poured in the cement within 2 minutes we have to place the mix in the wicked mold now the cement which is mixed just been transferred in the wicked mode so all these human mixtures will be transferred in the mood and it should be slightly damp which should be slightly Tamra so that the voids in the cement mixer will be clear and now the wicked mold has been placed at the bottom of the vaquita practice and now slowly gradually we have to remove now you could able to see zero is the reading so for the time zero is the reading after ten minutes now we are going to check again the reading so we are taking the time it's ten minutes is over so again now we have to slightly move the position which we have taken the first reading so now gradually it is left now it's again zero now again we are retaining it in the original position and we have to check we have to wait for the timing and after 25 minutes now again we are checking the time so after 25 minutes so we are slowly we are releasing the knob and the wicked needles goes and plunges inside the Moon now here you can able to find zero and this is 10 so this to the point indicates reading s2 now again these it is being placed in the original position so after 35 minutes now again we are checking the time so it is time is 35 minutes after 35 minutes we are again slowly removing and we are slightly shifting the mode to some other place and now we are checking the initial setting time the plunger penetrates into the mold and now you could able to see is 7 so the more pointer indicates 7 which is of 35 minutes
