The Silicate Mortar is basically used an acid resisting cement also better known as silicate base. The mortar offered by us is a general purpose cement for acidic conditions. Apart from this they are resistant to medium concentrations common organic & inorganic acids except hydro flouric acid. They are alo unsuitable for aqueous solution & alkaline conditions. They are best for for high temperature and where the concentration of acid is high.

Preparations of Silicate Mortar:

The amount of the mortar that is to be mixed is1 part of solution to suitable mixing pan.
Now you can add 3 parts of the powder slowly and gradually and continuously mix it thoroughly to form a smoother mortar.
In summers or in working areas that is hot large batches of mortar are not suitable as they become stiff and will dry rapidly. For this small batches not more than 4 to 8 kgs. Is best.
Further the mortar should be used completely before it starts getting set

Application of Silicate Mortar:

  • The Silicate Mortar is used for the jointing bricks that are acid resisting for construction of various vessels such as for fume chambers & stacks handling hot, dry acid fumes and vapors.
  • They are also suitable for jointing stoneware pipes that are resistant to chemical.
  • The offered cement is also suitable for the bedding material for bricks, tiles that are acid resistant.
  • Before the application of the mortar the concrete surface needed should be dried, clean and must be rough.
  • After the application of the mortar the bricks or tiles the mortar will be set over concrete surfaceon which it is applied forming a suitable an impermeable inter liner.
When Bedding and Jointing Materials are the same:
  • The surface, bricks or tiles that are treated must be bedded upto thickness of about 6 mm & then tamp gently with the help of a wooden piece so that the extra paste squeezes out of joints.
  • The amount of paste that is squeezed out from the joint should be immediately removed with the help of trowel for better finishing. The mortar of joint after getting dried must be treated with 20% hydrochloric acid solution using brush. The lining must be in contact with acid & not with water.
  • The concrete subtract such as floor, wall, tanks & similar surface are to be protected with bitrok mastic membrane. The steel tanks are to be protected with PVC according to the concentration of the chemical  & temperature of chemical. Apart from this the lining of the brick is over the protective layer of bitrok mastic.

The offered mortar is suitable for chemical plants, dye intermediates, & steel industries, textiles units, storage battery manufacturer, oil refinery, petrochemicals, fertilizers etc where acids like chronic, nitric, hydrochloric acid, phosphoric, sulfuric acids & dry acids & chimney lining work except hydro floric acid.

Shelf Life:
  • The shelf life is 1 year when it is stored at room temperature manufacturing date.
  • The physical properties of the mortar I.S. 4832 Part-I -1969 test requirements.

When Bedding and Jointing Materials are Different:

If the bedding and jointing materials are different you should spread the silicate mortar 6 to 8 mm thick on backside of tile or brick. After applying press the tile on leaving space for joints for bricks. When the mortar is set completely fill MP joints with specified cement.
