SPECIFICATION FOR MATERIALS FOR USE IN THE MANUFACTURE OF MAGNESIUM OXYCHLORIDE FLOORING COMPOSITIONS (

Second Revision )
0. FOREWORD:

0.1

This Indian Standard ( Second Revision ) was adopted by the Indian Standards Institution on 26 February 1982, after the draft finalized by the Flooring and Plastering Sectional Committee had been approved by the Civil Engineering Division Council.

6.2 Magnesium oxychlcride composition consisting of mixture of calcined magnesite filters and pigments provides a good floor if proper ingredients are mixed in correct proportions and skilled labour is employed in laying the floor. Too wet a mix with excess of magnesium chloride results in Mineral oils, greases or vegetab!e oils do sweating of the floor surface. The flooring is not seriously effected by alkalis, not affect the floor. but strong alkalis such as soda or harsh cleaning agents tend to attack the protective dressing and thus exposing the flooring to action of water. However, the finished floor needs to be protected from water or excessive moisture by periodic applications of wax polish or oil at regular intervals. 0.2.1 Magnesium oxychloride flooring should not be used in any situation where it woulcl be exposed to damp conditions for long periods, unless other suitable protective measures are taken. The flooring should not also be used in places where it will be exposed to acids or salts continuously. Under normal conditions proper waxing or oiling of floors will provide adequate protection against the attack of moisture. 0.3 This standard was first published in 1956 and subsequently revised in 1962. It has been revised again to incorporate the improvements found necessary in the light of the usage of this standards and in view of the experience gained during the course of these years. In this revision, a number of changes have been made; the most prominent being the inclusion of the physical requirements of calcined magnesite which in the eariler version was left to agreement between the purchaser and 3

IS : 657 - 1982 the vendor. The requirements of fillers like saw dust and wood flour have also been dealt in detail on the basis of actual invcsigations. The limit of grading for fillers and aggregates other tllan saw dust and wood flour has also been added and only Grade 3 of magnesium chloride has been allowed. The methods of tests have been separated and covered in IS :10032-1982*.
