Very informational video. Is there a reason to calculate the dry weight afterwards? Because i saw somewhere that the bricks were being dried in the oven beforehand for 24 hours and then dipped in water. Would be grateful if you could explain which would be the preferred method and why.
Simple way to find % of water for brick! Put the brick in water for while then take out and cut the brick in mid and see the cross section Eg; measure total cross section area is 4.5 * 3 =13.5 inch square' And dry space area is 4.3 * 2.8=12.08 inch square 12.08 divided by 13.5 and multiply by 100 = 89.481 And then 100-89.481=10.52 It means brick absorb 10.5 % water....'
I caught that too, however, moot point if trying to find the saturation amount of the bricks which is what this did. If measuring the lost volume of the water, then that would apply however that's a lousy way to measure due to evaporation. Maybe not following all standards, but did not matter in this case. Saturation then drying and using the difference would be the most accurate way. Only issue is the very minimal evaporation when transporting the bricks to the oven.

You are saying right... first dry on oven for 24 hours

And dry space area is
4.3 * 2.8=12.08 inch square
12.08 divided by 13.5 and multiply by 100 = 89.481
And then 100-89.481=10.52

kindly can u tell us according to which standard u performed this test..
u missed first step in which we put the bricks in oven to completely dry them and then they are weighed before putting in bath.

How can you water proof leaking chimney??
hi,may I ask what standard did you use
