PREPARATION OF LIME SPECIMENS WITH CLOSELY CONTROLLED PROPERTIES

A TECHNIQUE FOR PREPARING SOUND LIME (CALCIUM OXIDE) SPECIMENS WITH CLOSELY CONTROLLED PROPERTIES IS DESCRIBED. THE PROCEDURE INVOLVES CALCINATION OF THE CARBONATE, FOLLOWED BY COMPACTION AND LOW TEMPERATURE SINTERING OF THE CALCIUM OXIDE. GREATEST CONTROL OVER WATER REACTIVITY OF THE SPECIMENS IS ACHIEVED BY VARIATION OF THE CALCINING CONDITIONS. COMPACTING THE LIME AT VARIOUS PRESSURES PRIMARILY CONTROLS THE BULK DENSITY AND POROSITY. MEASUREMENTS OF THE APPARENT SPECIFIC GRAVITY, PERCENT POROSITY, BULK DENSITY, SPECIFIC SURFACE AREA AND AN AVERAGE PORE SIZE WERE MADE ON THE SPECIMENS. RESULTS COMPARED FAVORABLY WITH THOSE OBTAINED ON LIME PRODUCED FROM NATURAL CARBONATE MATERIALS. THE CHIEF DIFFERENCES BETWEEN THE TWO TYPES OF SPECIMENS SEEMS TO BE IN THE PORE STRUCTURE. /AUTHOR/
