USE OF SURFACE-ACTIVE AGENTS FOR DRYING CONCRETE AGGREGATES /IN RUSSIAN/

RESULTS OF LABORATORY TESTS ARE PRESENTED IN WHICH AGGREGATES, MAINLY SAND USED IN CONCRETE, WERE WASHED WITH WATER CONTAINING A VERY SMALL PERCENTAGE OF SURFACE-ACTIVE AGENTS. A COLUMN OF SAND, 10 CM. IN DIAMETER AND 5.5 M HIGH WAS USED FROM WHICH IT WAS POSSIBLE TO TAKE SAMPLES EVERY 0.5 TO 1 M. FOR MEASURING THE MOISTURE CONTENT OF THE SAND. SURFACE-ACTIVE AGENTS DECREASE THE QUANTITY OF WATER IN SAND HEAPS BY HALF, MAKING THE SAND NONSUSCEPTIBLE TO FROST; CONCRETE MANUFACTURED WITH THIS TYPE OF SAND SHOWS THE CHARACTERISTICS ASSOCIATED WITH THE USE OF WATER- REPELLANT PLASTICIZERS. /LCPC/RRL/
