EFFECT OF A POLYETHYLENE OXIDE ADMIXTURE ON THE STRENGTH OF CONCRETE

THIS ARTICLE GIVES SOME LIMITED TEST RESULTS FOR THE INFLUENCE ON THE WORKABILITY AND COMPRESSIVE STRENGTH OF A NOMINAL 1:2:4 CONCRETE PRODUCED BY A POLYETHYLENE OXIDE ('POLYOX WSR-301') ADMIXTURE AT HIGH RATES OF ADDITION OF 0.05 AND 0.10 PER CENT BY WEIGHT OF CEMENT. IT WAS FOUND THAT THIS ADMIXTURE REDUCED THE WORKABILITY OF THE FRESH CONCRETE TO SOME EXTENT, BUT IT HAD NO EFFECT ON THE RATE OF HARDENING OR ON THE COMPRESSIVE STRENGTH FOR CONCRETES STORED EITHER IN WATER OR IN AIR AT 65% RELATIVE HUMIDITY FOR PERIODS UP TO ONE YEAR. THERE SEEMS TO BE A NEED FOR MORE INFORMATION CONCERNING THE INTERACTION BETWEEN THE WORKABILITY AND PUMPABILITY OF CONCRETES CONTAINING POLYETHYLENE OXIDE. /AUTHOR/
