Title: FINAL REPORT ON SHRINKAGE-CRACKING CHARACTERISTICS OF STRUCTURAL LIGHTWEIGHT CONCRETE
Abstract:STRUCTURAL LIGHTWEIGHT CONCRETE, MADE WITH TWO TYPES OF COARSE AGGREGATE AND WITH TWO TYPES OF CEMENT (I AND III) WERE SUBJECTED TO TWO CURING PERIODS FOLLOWED BY A PROLONGED EXPOSURE IN A 140 DEG. F,...STRUCTURAL LIGHTWEIGHT CONCRETE, MADE WITH TWO TYPES OF COARSE AGGREGATE AND WITH TWO TYPES OF CEMENT (I AND III) WERE SUBJECTED TO TWO CURING PERIODS FOLLOWED BY A PROLONGED EXPOSURE IN A 140 DEG. F, 25% RELATIVE HUMIDITY ENVIRONMENT. UNRESTRAINED DRYING SHRINKAGE AND RESTRAINED CRACKING WERE DETERMINED. SIGNIFICANT FINDINGS INCLUDED (1) PROLONGING MOIST CURING RESULTED IN A MARKED REDUCTION IN DRYING SHRINKAGE, (2) ALTHOUGH THE USE OF TYPE III CEMENT RESULTED IN LESS UNRESTRAINED DRYING SHRINKAGE, IT CAUSED MORE RESTRAINED CRACKING, AND (3) THE COMPLETE ELIMINATION OF SHRINKAGE CRACKS APPEARS TO BE PRACTICALLY IMPOSSIBLE. /AUTHOR/Read More
