bricks
 
what every one think i recently took delivery of what they call 1st class bricks and nearly every one of the have a dent and chip, little ones, and over 100 had large chips and corners missing what's the grading in the UK like i have been told in the fire brick industry that's acceptable ???

It is not acceptable for firebrick in the U.S., although it won't really hurt anything.

The firebricks I can get here are nearly all perfect, but mind you, we are closer to China so less chipping in transport. :D

How can a premix NOT be wet?

When it's dry. Even if it were the right stuff, why pay refractory prices for water?

If its dry it hasnt been mixed, water is part of a mix for final application. No water means it still isnt mixed yet.

The problem with wet refractory cement is twofold. First, and not really that important is that it is water soluble. The interior of you oven should never get wet so this isn't a big deal. The important limitation of wet refractory cement is that is designed for joints less than 1/8". It has very fine aggregate and being wet it shrinks a lot, thus it cracks badly at anything over 1/8" in thickness. It also has very little in the way of adhesive properties.
