Borate compounds {i.e. borax, boric acid, Etidot 67 (disodium octaborate tetrahydrate)} convert to boric acid when they come in contact with wood whose pH is 4 – 5. In solution boric acid works as a weak Lewis acid which accepts an hydroxyl (OH-) to form a tetrahydroxyborate ion. The efficacy of borate compounds depends on the quantity of.

In this study, the use of borax waste as an additive in brick production was investigated. For the purpose of leaching treatment by soda solution was applied to recover B 2 0 3 and therefore to reduce the toxic effect of the waste.

After the leaching process, composition of the bricks was adjusted to cont 20, and 30% by weight-dried waste. In order to alleviate this problem, the possibility of using clayey tailings from a borax concentrator in red brick manufacturing was investigated.

Up to 30% by weight tailings addition was found. Tailings clay of Kirka Borax Plant, rich in boron compounds, was tested to determine if this material can be used as an additive in red brick manufacturing.

It was found that addition of this material up to 30% improved the brick quality with regard to compressive strength, water adsorption and density without compromising on other by: The possibility of using clay tailings from a borax concentrator in red brick production was investigated and up to 30% by weight tailings addition was found to improve the brick quality.

The effect of heat treatment on colemanite for the [9] Use of Borax Sludge as an Additive in Wall Tile. Prepare ml of borax (sodium tetraborate) 10% with enough phenolphthalein to produce a pink color.
