Refractory brick requirements for mortar

Refractory brick is a refractory material that we often use. It is indispensable in some masonry projects, so its quality must be strictly required. In our production process, mortar is a very important part, which can promote the formation of bricks, so when it comes to mortar, it can’t be casual, so let’s take a look at the requirements for the mortar during the production process. .

1. Proportion. Cement: Mortar: Construction glue = 1:2:0.03 (weight ratio).

2, cement. To use Portland cement, slag cement cannot be used, because the soluble salts in the slag can seep out from the pores of the refractory bricks, causing hoarfrost and affecting the appearance of the building.

3. Dry humidity. The mortar used for pasting the bricks should not be too thin, it should be better not to drip the mortar liquid, and the mortar used for jointing should be drier, looks loose, and can form a mass in the hand.
