How To Mix Refractory Mortar | How to use Fire Brick Cement

#homemade #DIY project #diy Build #firebricks #refractory mortar # heating element #tempering oven #heat treatment oven
Usage of refractory mortar are different but mostly we follow these ratios 10: 3 : 1.5 - Sand, Calcium Aluminate cement, Fireclay.

If you found hard locating refractory cement don't worry, here is one mixing formula with Portland cement plus lime available in ordinary building stores.

There are two Portland cement types, get the common gray in color, the other one is white decorative used for around pools etc. where a white effects are required.

Lime is calcium it takes over the cement in hot conditions (Portland will gradually burn out, it is used only for the mortar to set while working.)
10 : 6 : 2 : 3 – Sand, Fire Clay, Portland cement, and Lime.

thank you so much for showing concern about too much water or too wet. actually it was the requirement of the project and the heating oven we made 6 years ago is perfectly working fine and there are no cracks or any defect if you check other video you will understand properly.

So that was 6 handfuls of mix to 1.78 gallons of water?

I came here to learn something. I learnt a whole lot of nothing.

That mix has got at least the double of water that's supposed to have. Also you're supposed to leave the mix to rest for 5 minutes and then stir again. Also put the bricks in water for some hours and the ones I see are dry...

What do you fill the joints with after?

How do the bricks stick on the sidewalls when it’s soup? Same as nailing jello to the wall

You glossed over the part about mixing with a drill, paddle and bucket, need about 5 more minutes of footage.

Use Home Depot prism tile grout or any of their tile mortars with calcium aluminate.
Better yet is any tile grout from Mapie or their fast set tile mortar. Add in some fire clay/kaolin, silica sand and kyanite, (all cheap available at any pottery store ) and you have a refractory mortar for half price.
Or again pottery store get a bottle of sodium silicate.
Use 3 part silica sand, 1 part kyanite, 1 part kaolin then mix in sodium silicate until mix is consistency of butter. Half the price of air dry refractory mortar

Are these ratio’s by volume or weight?

Hi! Can I used cement for building of house instead?

[kryptoknight]

What are the ingredients?
Let me know the mixing ratios please...???

[theonlybuzz]

???? Could have been better, i would have hoped for some more explanation, rather than a fast beat music and silence.

[pezgallo]

These boys waste a lot material and make one hell of a mess...

[donpayne]

Worthless video, at least it was less than two minutes

[markgiles]

Hi. Should one use High-Temp mortar with sand only to use as a liner for a hobby kiln to melt Aluminium?

Mix clay with foaming agents in a cement mixer and you'll have a cheaper alternative to aircrete or furnace cement.

Furnace cement is basically clay, but aerated and more lightweight. It has to be aerated so R-value will be greater than clay alone.

[finarya]

Can this cement used for aircrete or CLC?

Acme Brick sells one gallon tubs of this stuff in stiff form and you add water to the consistency of heavy cream, dip the bricks and lay brick to brick.
