EFFECTS OF CURING AND DRYING ENVIRONMENTS ON SPLITTING TENSILE STRENGTH OF CONCRETE
THE SPLITTING TENSILE STRENGTHS OF LIGHTWEIGHT AND NORMAL WEIGHT CONCRETES WERE INVESTIGATED IN TWO TEST SERIES WHICH DEALT WITH THE EFFECTS OF THE CURING AND DRYING ENVIRONMENTS. THE FIRST SERIES SHOWED THAT THE DURATION OF THE INITIAL MOIST CURING PERIOD PRIOR TO DRYING AT 50 PERCENT RELATIVE HUMIDITY HAD LITTLE EFFECT ON THE SPLITTING STRENGTH. WHILE THERE WAS A LOSS OF SPLITTING STRENGTH FOR THE LIGHTWEIGHT CONCRETE EARLY IN THE DRYING PERIODS, CONTINUED STORAGE IN THE DRYING ATMOSPHERE LED TO CONSIDERABLE GAIN IN THE SPLITTING STRENGTHS. IN THE SECOND SERIES, CONCRETES WERE SUBJECTED TO DRYING FOR 21 DAYS AT DIFFERENT LEVELS OF RELATIVE HUMIDITY AFTER INITIAL MOIST CURING FOR 7 DAYS. ONLY MINOR CHANGES OF SPLITTING STRENGTH WERE FOUND AS THE RELATIVE HUMIDITY VARIED FROM 75 TO 10 PERCENT. /AUTHOR/
