DETERMINATION OF SPECIFIC GRAVITY AND ABSORPTION IN DRY AGGREGATE /IN SPANISH/

A MODIFICATION TO ASTM C 127-51, USED IN SPAIN UNTIL NOW FOR THE DETERMINATION OF SPECIFIC GRAVITY AND ABSORPTION IN DRY AGGREGATE IS PROPOSED. TO PREVENT HUMIDITY LOSSES WHEN REMOVING THE SURFACE PARTICLES, THE WEIGHT SUBMERGED IN PARAFIN IS DETERMINED, CALCULATING THE SPECIFIC GRAVITY USING FORMULAE WHICH INCLUDE TH DENSITY OF THE PARAFFIN. THE REPRODUCIBILITY OF THE TESTS IS BETTER THAN THAT OF THE ORIGINAL STANDARD AND ALTHOUGH THE SPECIFIC GRAVITIES OBTAINED ARE PRACTICALLY IDENTICAL, THE DIFFERENCES ARE MORE NOTABLE IN THE ABSORPTION VALUES. /LTE/LCPC/RRL/
