Clearly explained video.The narrator has a very clear voice.Well done.

[@jayavardhans316]

Mam plz tell me about limestone ingredients

[@nickwilson7929]

*She is explaining everything so clearly 😊*

[@glibble_gobbler]

I never realized how good youtube videos helped. very clear voice and the summary helped a lot thanks!

[@fuseschool]

Awesome! Glad to hear it! And glad it helped 🙂

[@mumu1211]

it is pretty clear, good visual

[@YouMockMe]

Wow! This video exceeded expectations. ...way to raise the bar, thanks!

[@Michealfarmer]

Thanks for the great video. I have cooked limestone in the past and was amazed after I let I cool and then dipped a piece of the stone into water. The solid superheated and began to disintegrate in front of my eyes. My children thought it was great, I thought it was awesome! I have been trying to make a decent concrete from the slacked lime. Sadly it disintegrates fairly easily after drying. I still have some learning to do.

[@TheEjsc]

You need the organic matter to make it strong again is not strong because you removed the organic with fire. If you find out how to put it back let please let me know. I'm looking into how the Aztecs used CaCo3

[@rishikaagrawal1246]

Amazing presentation... Everything is now crystal clear!! Thanks so much....

[@fuseschool]

You're very welcome! 💜

Thank u so much for explaining this clearly

You're so welcome! 🤗

[@petergambier]

Nicely explained video.I use lime putty in my work and much prefer it to cement and hydraulic lime.One question,why does hydrated lime not set? Also, somebody once explained that the difference between lime and cement is not only does lime use less energy to produce it but cement has clay in it which makes it non-porous and yet if you want your lime putty mortar to set faster you can either add a pozzilan or else add powdered clay,but surely that's turning it into a cement which defeats the object of using the lime putty doesn't it?

[@PeterrAre]

it sets slowly as it reacts with atmospheric CO2. Yes clay is one source of material to make cement but not the only one. A few different processes go on in cement, some responsible for early set, some for slow strength development, all related to chemical hydration. Just what I remember from my civil engineering days

[@corindoyle]

There are degrees of hydraulicity and as a result flexibility and breathability too. Cement is at the top, putty at the bottom with NHL's in between. Eg. adding metakaolin to hotmixes makes them as strong as NHL3,5. Lime putty is only really for fine plaster you should use hot mixes. Hydrated does set, just very slowly and you could add a pozzolan like brick and just use it like NHL if you really wanted to. Hydrated is from the same lime as putty but with 10-15% water added as oppossed to 100% for putty and non for quicklime.

Superb explaination

superb video easy to understand

[@fuseschool]

Glad to hear that!

[@Zloner]

Limestone or calcium carbonate can be soluble in acidic pH. if more CO2 will be introduced to the solution (giving temperature is low enough) it will be dissolved again to Ca and CO3

[@Medic704]

Amazing explanation

[@fuseschool]

Glad you think so!

[@cow123456789chicken]

when adding co2 to lime water to make caco3 would it be a solid? if not would it be solid once exposed to air?

[@sangeetarajput5398]

How is Sodium Hydroxide different from Calcium Hydroxide please? is it a lot different?

[@militarytechtrack202]

Nice work

[@fuseschool]

Thanks!

[@sadaffatima5371]

Very nice video and indeed helpful. There is a query, is it possible to collect carbondioxide in a gaseous state from calcium carbonate thermal decomposition?

[@fuseschool]

Since the gases coming off from limekilns are almost pure carbon dioxide it would be sensible to try to capture it - perhaps by pumping it into old gas or oil wells. Currently in UK some research has been undertaken but it is in its early days. www.gov.uk/guidance/uk-carbon-capture-and-storage-government-funding-and-support

[@sadaffatima5371]

@@fuseschool Thank you very much. Just one question, is it possible to collect carbondioxide in a gas storage bag or some glass vessel? Just a Laboratory scale experiment.

[@private_july]

..what can you say about calcium carbonate suplements?

thankyou mam

[@sanjibsarkar1261]

Kindly name the apparatus in which caco3 is getting decomposed . I'm finding difficult to comprehend the accent you applied in speaking it's name .

[@fuseschool]

1:33 Limestone can be thermally decomposed in a rotary kiln.

[@Esu9830]

super madam

[@andys9566]

How come this useful thing got less view?

[@alik3676]

Andy S Because this is a copy of the original just with a starting bit...

[@frankfranchesko2687]

Because no one want to use their had anymore.

Nice

Thanks

The hydrogen carbonate formula is Ca(HCO3)2 not CaHCO3

[@sakshamsaklani1554]

No bro its CaHCO3 only, who told you it is Ca(HCO3)2

[@resdfredsf4930]

i like her voice😊

[@batmanbegins72]

what is the exact heat ?

[@omsingharjit]

800c as far i know

great work.....now ....ersatz milk......yeahr.

What!? 0:55, Millions of years ago? This process can occur in a much much smaller time frame, like thousands of years. Lets not blame everything on large numbers for convenience.
