Basic Steps for Rapid Polished Section Preparation

BASIC STEPS FOR RAPID POLISHED SECTION PREPARATION 

The procedure described here is an outline of recommended steps, not to be taken as unalterable, in the production of polished sections of whole clinkers or a sieved fraction of crushed clinkers. The recommended procedure involves the use of epoxy resin, a rotating-wheel grinder/polisher and a tabletop saw. An elapsed time of less than 30 minutes is typical for the proposed procedure by which a virtually flawless polished section is produced. Following are the basic recommended steps  

Vacuum impregnate the clinker fragments or whole clinkers with epoxy resin. 

Cut with the small tabletop saw or grind the base of the encapsulation to expose the particles. 

Grind the exposed surface with the grinder/pol-isher using No. 320 adhesive-backed, silicon-carbide paper for approximately two to three minutes.
